James Franco and Anne Hathaway performing Grease tribute?

James Franco and Anne Hathaway could very well be journeying back in time to recreate a classic scene from musical Grease for this Sunday’s Academy Awards. Footage of the pair re-enacting that film’s climactic carnival scene has been posted online by Franco himself, who we all know likes to play around with cameras. It’s most likely that this is footage of the Oscar hosts filming a segment for the ceremony, but could it be something else?
