Lovely, shapely and appealing blonde actress Mary Louise Weller was born on September 1, 1946 and raised in Los Angeles. The onetime top New York model made her film debut with an uncredited tiny role in the superbly gritty cop drama Serpico (1973). Weller was especially memorable as a beautiful marine biologist in the made-for-TV picture Hunters of the Reef (1978) (TV) and, likewise, solid as professor Andrew Prine's college student lover in the superior haunted house horror winner The Evil (1978). Mary achieved her greatest enduring cult movie popularity with her excellent and inspired performance as snooty and uptight sorority snob "Mandy Pepperidge" in the uproariously raunchy'n'raucous hit comedy Animal House (1978). After "Animal House", Weller went on to play the sole non-suicidal character in The Bell Jar (1979), Martin Kove's fetching wife in the cruddy "Jaws" rip-off Blood Tide (1982), Chuck Norris' girlfriend in the exciting martial arts action opus Forced Vengeance (1982) and a funny small part in Larry Cohen's terrific tongue-in-cheek monster-on-the-loose treat Q (1982). Mary had guest spots on the TV shows "Quincy M.E." (1976), "Fantasy Island" (1977), "Supertrain" (1
