Another example of using comedy for good today: Lucasfilms has collaborated with Stand Up to Cancer to make this Star Wars themed video tribute featuring Aziz Ansari, Zach Galifianakis, Ed Helms, Ken Jeong, Seth Rogen, Andy Samberg, and Emma Stone acting out lines from (the best movies of) the Star Wars series. Stand Up to Cancer funds a variety of innovative and collaborative research projects that are working towards a cure.
Good nerdy fun and all for a good cause.
