Frank Coghlan Jr's cameo in this episode happened
pretty much by accident! In an interview with P.C. Hamerlinck
in FCA, Coghlan revealed that Arthur Nadel, who was the
director of this episode, visited the Los Angeles Zoo (where
he was the PR director) asking to arrange a time to use the zoo
for location filming. When Coghlan mentioned that he played Billy
Batson in the 1940s "Adventures of Captain Marvel"
serial, Nadel couldn't believe his ears and promptly had a part
specially written so that Coghlan could appear.
Steve Gustafson (Alan) is perhaps best known for being
a member of the Short Circus on the popular PBS series The
Electric Company. His small handful of acting credits also

guest shots on such shows as Land of the Giants, Brady Bunch,
Marcus Welby M.D., Adam-12 and Emergency! He also
was in a couple of TV movies as well as the big-screen film "The
Cowboys," as well as the short-lived TV series that followed
a few years later.

of guest appearances on Partridge Family as Punky
Lazaar, and guested on several other shows, including Family
Affair, Green Acres, Land of the Lost, Mannix, CHiPs, Vega$,

and movie appearances while still a teen, including an episode
of All in the Family and the movies "What's
the Matter With Helen", "Hickey and Boggs" and
"I Love You, Goodbye." There is no record of any acting
credits for her after 1974.
Scott Garrett (Jerry) acted in TV and movies up until 1980. Some of his
other credits include Family Affair (playing two different
characters in four episodes), Adam-12 and Little House
on the Prairie. His movies include "Watermelon Man",
"Magic" and the coming-of-age picture, "Foxes".
Frank Coghlan, Jr. (zookeeper)
got his showbiz start in silent
movies as an extra at age 3. He soon because a popular child
actor, but the coming of "talkies" (and his adolescence)
reduced him to getting smaller roles. After a career landmark
starring as Billy Batson in the "Adventures of Captain Marvel"
serial, Coghlan went off to participate in World War II as an
aviator. While with the military, he acted as a liaison between
the Navy and the Hollywood studios. After the War, he decided
to stay in the military and upon retirement in 1965, he has since
returned to TV and movies, wrote an autobiography, did commercials,
appeared on game shows like Scrabble and Wheel
of Fortune and still made many movie convention appearances
(for his Billy Batson role) up into his 80s.
Although he officially retired
from acting in 1969, a call from Filmation Studios led him back
out one last time to appear in this episode of Shazam!
so that fans would be able to see the two Billy Batsons meet
face to face.
