Melissa McCarthy has been drumming up Oscar buzz for her performance in the upcoming drama Can You Ever Forgive Me?, and it's not hard to see why. In this exclusive clip, the actress — who's known for her exceptional comedic talents — shows off her dramatic chops as Lee Israel, a real-life magazine writer whose life began spiraling downward after she started forging and selling letters that she claimed had been written by late, great writers. In the footage above, she has a tense conversation with Jack Hock (played by Richard E. Grant) at a bar, which has us more excited for the twisted biopic to come out than ever. Give the scene a watch before Can You Ever Forgive Me? hits theaters on Oct. 19.
