James Franco "leaked" this preview of the Oscars dance number on his Twitter feed:

If they wanted to make it look like someone shot this with an iPhone and sent it to YouTube IN SECRET! they couldn't have done a worse job. It's been run through some filters to desaturate it and make it look like an old home movie; at :03 it looks like scratchy film leader, which are not found on cameras that do not actually use film; same effect at :13 except it's transparent. Someone went to a lot of trouble to make this look "authentic."
