'9 to 5' (1980)
You can imagine the appeal of a comedy that revolved around a workplace revenge fantasy — specifically, a revenge fantasy focused on the embodiment of a condescending, sexually harrassing, male chauvinist pig of a boss. There were over 45,000 women in the workforce in 1980, and when they weren't bruising their head against the glass ceiling, most of them had undoubtedly dealt with someone like Dabney Coleman's corporate dickwad Franklin Hart, Jr. Combine that wish-fulfillment factor with one supergroup of a female cast (Oscar-winning actress Jane Fonda, groundbreaking comedienne Lily Tomlin and, in her movie debut, country-music legend Dolly Parton), and no wonder the movie was a huge hit. Most people probably remember Parton's chart-topping theme song over the film, but it was a major milestone in female comedies...not that it caused studios to rush out and greenlight a gajillion big-budget all-lady yukfests.
