Theresa Tilly made a monstrous feature film debut as Shelly in Sam Raimi's influential classic, The Evil Dead (1981). After working as a stand-up comedian in her hometown of Detroit, she set her sights on acclaimed improv comedy troupe The Second City Chicago. Her work there earned her a role on a sketch comedy pilot called YouTV, co-starring alongside late-night TV legend Steve Allen. Although the show was not picked up, it served as an impetus for the budding performer to move to Los Angeles in order to pursue her acting career.
