Having secured the return of Heather Graham but presumably still looking to up its non-male quotient, The Hangover Part III is courting Melissa McCarthy for a small role. That’s vague, so we can certainly hope it not only comes together but winds up being more of a multi-scene-stealing role, less a cameo. We’ll see — McCarthy is pretty busy between Mike & Molly and the Sandra Bullock buddy-cop movie she’s got in the works.
