Charlize Theron has an Academy Award for acting and even she can't pretend to be enthused to be on 'The Tonight Show with Jimmy Fallon'.

Theron's 'Atomic Blonde' press tour is apparently never-ending and last night's stop included a randomly generated dance move battle that came complete with Fallon taking the piss out of Theron's accent in the film and must have been a delight for her to sit through.

Introducing the world to the 'Slap the Giraffe' and 'The Tennis Pro' as well as teaming up with Fallon for the 'Double Kayak', Theron's upper lip was so stiff it almost looked like she was having fun and while she committed to the dancing, you could tell she would rather have been anywhere else.
