24. JENNIFER JASON LEIGH VS. BRIDGET FONDA IN SINGLE WHITE FEMALE (1992)
It's not the sexiest fight scene on the list, but Jennifer Jason Leigh and Bridget Fonda’s brawl from Single White Female is the most brutal, and perhaps scariest, girl-on-girl spat we have ever seen. Playing the deranged Hedy, Leigh goes to bizarre, and homicidal, lengths to make sure her roommate, played by Fonda, never leaves her.
Their fight at the end of the film is completely chilling and hard-hitting with more than enough emotion to be believable. There is no fancy choreography or skimpy outfits here; instead, these two just take it to each other in about as vicious a manner as possible.
