You know that thing that happens when a comic actor starts getting some mojo, so they’re thrown into every movie possible? McCarths is in that phase. She has been cast for an unspecified role in Hangover III. The script probably just read, “Woman, 30s” and they’ll just have Melissa fill out the role with her McCarthyism. Maybe, she and Zach’s character will go on a date and split a bottle of ranch dressing.
