I know him from Even Stevens, and Holes (a movie which is not at all memorable to me), and Charlie's Angels: Full Throttle, and Constantine, and the Transformers movies.
I know him from an episode of The Odyssey, and Dead Last, and Invasion, and That Was Then (which only lasted one episode, if I recall), and an episode or two of Jake 2.0, and a bit of Boston Legal, and Reaper, and Sons of Tucson, and Mad Love, and Deadbeat, and a very small role in an episode of The X-Files (season 10).
Lander, David L.
I know him from Laverne & Shirley, and small roles in A League of Their Own and Zoom: Academy for Superheroes, and some voice work.
There's a recurring role on Modern Family, and he was in Mirror Mirror, and The Nutcracker in 3D. And surely I must have seen some of his other live-action work, but mostly I know him for voice acting.
I always liked him on Night Court, and The John Larroquette Show. And in The 10th Kingdom. And an episode of Almost Human. And there was a cameo in Demon Knight. And maybe some other stuff, I don't recall.
I probably first saw him in Blackadder (from the second series onward), which is of course awesome. I'm vaguely aware of his work in A Bit of Fry & Laurie and Jeeves and Wooster; I should definitely try to see more of those things, someday. And there was a small role in The Borrowers. I suppose I know him best from House, in which he's quite good. And he voiced the Easter Bunny in Hop, and Dr. Cockroach in Monsters vs Aliens. And I feel like I must've seen him in other stuff. And I'm sure he's done plenty of things I'd like to see someday.
I know him from Gattaca; and The Talented Mr. Ripley; and I Heart Huckabees; and Sky Captain and the World of Tomorrow; and The Aviator; and The Imaginarium of Doctor Parnassus; and the Sherlock Holmes movies; and The Grand Budapest Hotel. And voice work in A Series of Unfortunate Events; and Rise of the Guardians.
I know him from The X-Files, and Andromeda, and Kyle XY, and V (2009), and an episode of Supernatural, an episode of Once Upon a Time, a few eps of Arrow, and probably some other stuff.
I know him from Roar; and 10 Things I Hate About You; and A Knight's Tale; and Casanova; and of course The Dark Knight; and The Imaginarium of Doctor Parnassus. I also saw him in The Brothers Grimm, but somehow never managed to recognize him at all. I wasn't really into that movie, anyway.
I know him best as Saruman in the Lord of the Rings movies and as Count Dooku in the Star Wars prequels. I sort of know him from a couple of Hammer films that I don't care about. There's also Return from Witch Mountain, which I only barely care about. And there's Sleepy Hollow, and Gormenghast, and The Golden Compass, and Season of the Witch, and Dark Shadows, and some voice work.
I know him from Super Mario Bros., and Romeo + Juliet, and Moulin Rouge!, and The Happening, and Kick-Ass 2, and voice work in Titan A.E., and Ice Age.
I know him from SCTV, and Bride of Boogedy, and American Pie, and Greg the Bunny, and he voiced Charlie in Finding Dory.
I mainly know him from The Guild and his vlog and other stuff on Geek & Sundry (such as Werewolves), but I also occasionally see him pop up in small guest roles in various things (generally so small they're not even worth mentioning), or in commercials (such as Fueled by the Future). Also there was a very small role in Hail, Caesar!
Um, I saw The One. That was sorta interesting I guess. And he was good in The Forbidden Kingdom and The Expendables. And I feel like I shoulda seen more stuff, but I can't think of anything. I'm sure it'd be nice to see more of his work though.
I know him best from 3rd Rock From the Sun. There's also Footloose; and The Tuskegee Airmen; and a few episodes of How I Met Your Mother; and Interstellar; and Trial & Error; and I'm sure I've seen him in some things that I don't really remember. Also he's done some voice work, including Shrek and Once Upon a Time in Wonderland.
There was Big, Sunday Dinner, Innocent Blood, Independence Day, an episode of the re-imagined Hawaii Five-0, a memorable Minute Maid commercial, a minor role in the miniseries Joan of Arc, and voice work in Oliver & Company.
There's Saturday Night Live, of course. Also My Stepmother is an Alien, and A League of Their Own, and NewsRadio, and I Could Never Be Your Woman, and Southland Tales, a couple eps of New Girl, a very small role in Three Amigos, and some voice work.
I probably saw Dune at some point, but I don't really remember it; I need to see it again. I saw Blue Velvet once, but I don't remember anything about it, and I don't think I cared for it. I've never seen Twin Peaks, but I've always really wanted to, and I'm sure someday I will. I mainly know him from Desperate Housewives. There was also Mysterious Island, several episodes of How I Met Your Mother, Believe, Agents of SHIELD, and The Librarian: Quest for the Spear. He also voiced Superman in Justice League: The New Frontier.
Macy, William H.
Let's see, there's Pleasantville, and Mystery Men, and Sports Night, and Bart Got a Room, an episode of Nightmars & Dreamscapes, and Jurassic Park III, and probably some other things I don't remember as well...
I liked him in the Spider-Man movies, of course. And Pleasantville. He was alright in The Good German. And The Cider House Rules. Maybe some other stuff.
Mainly know him from Firefly and Serenity. But there's also an episode of Human Target, an episode of Warehouse 13.
First and foremost, there was The Six Million Dollar Man (and of course The Bionic Woman). I also enjoyed his work in Raven, and wish the show would've lasted longer. There's an ep of Jake 2.0, the TV movie Ben 10: Race Against Time, an ep of Community, an ep of Human Target, and... I dunno what else.
Mako See voice actors M-N
Obviously, there's Being John Malkovich, which was really trippy. There's also The Hichhiker's Guide to the Galaxy; and Art School Confidential; and Mary Reilly; and Warm Bodies; and Beowulf; and Crossbones (though I only watched a couple eps of that); and RED. Oh, there's a commercial for iPhone.
I'm afraid I'm not terribly familiar with his early work as half of the comedy duo Cheech & Chong. But there was The Golden Palace, Nash Bridges, a few episodes of Lost, an episode of Psych, a small role in Race to Witch Mountain, and some voice work.
Mainly know him from Buffy the Vampire Slayer and Angel. But there was also a recurring role on Smallville, plus a couple episodes of Torchwood, and Caprica, an episode of Warehouse 13. And Dragonball Evolution. And the first ep of the reimagined Hawaii Five-0. And an episode of Supernatural.
I mainly know him from 30 Rock. Also there's Forgetting Sarah Marshall; an episode of New Girl; an ep of The Big Bang Theory; and some voice work.
The first thing I remember him from is The John Larroquette Show. That was good. Really liked his work in Pushing Daisies. And he was decent in Human Target. And an episode of Psych. And Waiting... I may have seen more of his work, I'm not sure.
I know him from Tin Man, and Desperate Housewives (season 5), and Captain America (and other MCU stuff), and Arrow (season 4), and undoubtedly some other things I've forgotten. Also some voice work, including (ironically) Green Arrow in a DC Showcase short.
I know him from A Clockwork Orange; and maybe Time After Time (though I don't quite remember it); and Star Trek: Generations; and Tank Girl; and an episode of Psych; and a few eps of Community; and Doomsday; and The Company; and a minor role in The Book of Eli. And he's done some voice work. Plus some Sprint commercials.
I know him best from My Secret Identity. But I also saw him in a few eps of Cheers, an ep of Who's the Boss?, a small role in Northpole: Open for Christmas, and probably some other things I've forgotten. Oh, and I once saw him do a car commercial; I forget what make, but I assume it was German, because there was a really bad pun involving the price $9999 and the word "nein."
Okay, there was Trainspotting, and A Life Less Ordinary. Good stuff, but I mainly remember him from the Star Wars prequels. Also he was pretty good in Moulin Rouge. Not sure if I've seen him in anything else, but no doubt I will eventually.
I know him from Simon & Simon, and Major Dad, and Undercovers, and a recurring role on Fairly Legal, and a couple episodes of Castle.
Know him best as Chief O'Brien from Star Trek: The Next Generation and Deep Space Nine. But there are various other things, including The Commitments, Far and Away, the pilot episode of Dr. Quinn, Medicine Woman, probably some other stuff.
Knew him first from This Hour Has 22 Minutes, which was fun. Then there was Made in Canada, also cool, though I didn't see as much of it as I'd have liked. And maybe some other stuff... (I should probably put him on the comedian links page, though. Eh, maybe I'll move this later.)
Miller, Jonny Lee
I know him best from Elementary, but there's also Hackers, and Trainspotting, and Dracula 2000, and Dark Shadows, and possibly things I've forgotten.
Let's see, I know him from several eps of Mad About You, the TV movie Karroll's Christmas, a few eps of Boston Legal, there's the series 10 Things I Hate About You, small roles in Kiss Kiss Bang Bang and Get Smart and God Bless America, and some voice work.
Of course there's Fantasy Island, though I remember that but little, from when I was quite young. Plus the "Space Seed" ep of Star Trek, which of course led to the movie Star Trek II: The Wrath of Khan. Great stuff, and I may have seen him in other stuff, I'm not sure. Probably some commercials. I feel like I must've seen him hawking coffee at some point, and of course there's something about "rich Corinthian leather." I dunno. But I'm also a fan of his voice work.
I know him from SCTV, and the Ghostbusters movies, and Strange Brew, and Little Shop of Horrors, and Rocket Boy, and Spaceballs, and Honey I Shrunk the Kids (and its sequels), and probably other stuff...
Morgan, Jeffrey Dean
I liked him in Supernatural, and Watchmen, and maybe some other stuff, I dunno...
Of course he played Lennier, one of my favorite characters on Babylon 5. And of course he was on Lost in Space. And one of the most memorable episodes of The Twilight Zone ("It's a Good Life").
He was good on Love & War, Dharma & Greg, an episode of My Boys, and in God Bless America. Also some voice work.
