From the book Cult Movie Stars by Danny Peary (New York: Simon and Schuster, 1991), pages 219-220:

CRISPIN GLOVER (1964-) Thin young actor, with sharp features, an awkward haircut, a nasal voice, a nervous laugh, a giddy smile, and strange eyes, has specialized in young crazies and eccentrics. One might have predicted an unusual career when he g ot a meat cleaver stuck in his face in Friday the 13th - the Final Chapter. He later made an AFI student film in which he made himself up like Olivia Newton-John and sang one of her songs. It wasn't released. But enough of his films have been rel eased to reveal a most bizarre talent who has both impressed and annoyed us with his mannered, inspired portrayals. He was quite hilarious as Michael J. Fox's hopelessly nerdy father in Back to the Future. His sicko teenager in the disturbing River's Edge, who forces his friends to keep secret a classmate's murder, is brilliantly conceived and played, but truly unappealing. Some viewers were turned off by an actor who could get into the brain of such a detestable character. In John Boorm an's off-center Where the Heart Is, he is no less kooky than anyone else, as a struggling, supposedly gay hairdresser who finally admits - as audiences hiss - that he's straight. Moviegoers are curious about but also fearful of the characters he' ll create in the future. He released an album called The Big Problem. The son of actor Bruce Glover.
