Chemo and tears alert.
I think it's only a matter of time before Joseph Gordon-Levitt receives some leading role recognition. He's dabbled in such with The Lookout, and (500) DAYS OF SUMMER, but has mostly seen success with supporting roles: Inception and the upcoming THE DARK KNIGHT RISES most recently.
What's so great about JGL is how he can go from suave action star to weak cancer stricken patient as you'll see in the new trailer for 50/50, a new film by Jonathan Levine (ALL THE BOYS LOVE MANDY LANE). 50/50 also stars Seth Rogan, Anna Kendrick and Bryce Dallas Howard; as well as a looks-to-be hilarious turn by Phillip Baker Hall.
