Loquasto began working in features in 1979 with "Sammy Stops the World", an adaptation of the Anthony Newley-Leslie Bricusse musical "Stop the World--I Want to Get Off", starring Sammy Davis Jr. In 1980, he began a long collaboration with director Woody Allen by providing the costumes for "Stardust Memories". The designer earned Oscar nominations for his work on three subsequent Allen films: the costumes for "Zelig" (1983) and the opulently detailed period production design on "Radio Days" (1987) and "Bullets Over Broadway" (1994). Loquasto has also designed Penny Marshall's "Big" (1988) and two features for Susan Seidelman, the contemporary "Desperately Seeking Susan" (1985) and the extravagant "She-Devil" (1989).
