Charlize Theron appeared on "Jimmy Kimmel Live!" to jump start the press tour for "The Old Guard 2," her upcoming Netflix action sequel. The tentpole finds Theron facing off against one of her action heroes: Uma Thurman. "We knew each other kind of offhand, but I knew her from being a massive fan, just watching her work, and always wanted to do something with her," Theron told Kimmel. "Because when I came into the action world, she was really, to me, like, the sensei. She was the OG."

Tarantino's "Kill Bill" movies were released in 2003 and 2004, turning Thurman into an icon of the action genre and an inspiration for Theron. "She should've won the Academy Award for 'Kill Bill,' right?" Kimmel asked Theron. "A hundred percent," Theron answered, adding that it's usually just "men who get a lot of credit for these [types of] movies. What she did in that film was just so unbelievable." Theron said she was "scared" to go head to head against Thurman in "The Old Guard 2," adding: "She's just such a badass. So since I've been in action movies I've been like, 'Who do I want to work with and do an action sequence with?' It's always been Uma Thurman. Always."

Theron returns for the sequel alongside original co-stars Kiandra "KiKi" Layne, Matthias Schoenaerts, Marwan Kenzari and Chiwetel Ejiofor. Thurman is a new addition alongside Henry Golding.
