Charlize Theron appeared on "Jimmy Kimmel Live" and dished about her latest movie, as well as what it's like to go on the show under the influence of pain medication.
She went on to say that her periodontist said he watched her late show appearance and, unimpressed by what he saw, told her that it wasn't a good idea to go on TV while on pain medication.
"If it makes you feel any better," host Jimmy Kimmel said, "at least half of our guests are medicated in some way when they come on the show."
Theron is starring in the upcoming "Atomic Blonde," a spy-action flick based on the graphic novel, "The Coldest City" by Antony Johnston and Sam Hart.
The movie is set for a July 28 release.
