The groundbreaking sci-fi film E.T.: The Extra-Terrestrial (1982) gave the actress a chance to show off her skills alongside a cast of gifted young actors that included Henry Thomas and Drew Barrymore. The following year, she starred in the high-profile horror project Cujo (1983), protecting a young Danny Pintauro from a rabid dog. But as well-known as those films have become, Wallace has never enjoyed the same name recognition.
Other notable credits include The Stepford Wives (1975), The Hills Have Eyes (1977) and The Howling (1981).
