Dailies | Emma Stone and Seth Rogen Use the Farce in ‘Star Wars’ Spoof (Video)

"The Help" star and a host of others help Stand Up to Cancer by goofing on George Lucas' classic space opera

Emma Stone, Seth Rogen and a host of other celebrities are taking the "Spaceballs" slogan "May the Farce Be With You" to heart.

Stone and Rogen — along with Samuel L. Jackson, Zach Galifianakis, Aziz Ansari, Bill Hader, Ed Helms, Ken Jeong, Jamie King and Andy Samberg — tackle George Lucas' space opera "Star Wars" in a new parody video, re-creating scenes from the classic sci-fi films with a wise-acre twist.

The spoof is more than just an opportunity to poke fun at Lucas' galactic epic; it also promotes the Use the Force for Good campaign, which benefits Stand Up to Cancer. In addition to a line of "Star Wars" T-shirts for sale, the campaign includes an eBay auction, with prizes that include a dinner date with Lucas, Lucasfilm alum John Lasseter and Francis Ford Coppola.)

Plus, the video answers the age-old question: Who would look better rocking the Princess Leia buns, Emma Stone or Zach Galifianakis?
