First gaining notice in the low-budget teen flick Senior Week (1987) , Elvis lookalike St. Gerard sky-rocketed to stardom as '60s teen heartthrob Link Larkin in John Waters's camp classic Hairspray (1988). St. Gerard portrayed the King of Rock four times: in the films Great Balls of Fire and Hearts of Dixie (both 1989), the 1990 miniseries Elvis, and on a 1994 episode of Quantam Leap. His last known acting appearance was an episode of Law & Order.
