‘Avengers’ Director Joss Whedon Gathers Film and TV Stars for Voting Ad

Marvel moviemaker Joss Whedon has returned to Twitter after a 12-month absence to launch a star-studded new Get Out the Vote campaign called “Save The Day.”

The Avengers director enlisted Keegan-Michael Key and Avengers co-stars Mark Ruffalo, Robert Downey Jr., and Scarlett Johansson to help urge Americans to vote in November’s presidential elections.

“You might think it’s not important, you might think you’re not important,” Ruffalo says in the video, before a string of celebrities add, “and the only way we can prove that to you is to show you lots of famous people… show you how important… it is.”

“And if you do vote,” the stars add, “Mark Ruffalo will do a nude scene in his next movie,” much to the Hulk actor’s chagrin.
