To fill in after Hack left the show, model and former dance instructor Tanya Roberts was cast as the street-savvy Julie Rogers, adding a very different Angel archetype to the series. She had had steady acting roles since 1975, but Charlie's Angels would be the first highly-visible role for her. It wouldn't be the last.
In 1982, she played the sexy love interest in The Beastmaster, a sword-and-sorcery barbarian movie. Continuing with the scantily-clad fantasy tradition, she played the titular character in Sheena: Queen of the Jungle in 1984. Soon afterward, Roberts had the distinction of playing Stacey Sutton, the Bond girl in 1985's A View to a Kill.
Modern audiences will probably best recognize her as Midge Panciotti on That 70's Show, a role which she played for six years. She ultimately left the show rather suddenly to spend time with her ailing husband, who passed away in 2006. She seems to be firmly out of the limelight these days, though she did write the forward to The Q Guide to Charlie's Angels, published in 2008.
