Tilda Swinton, 'Trainwreck' (2015)

The latest example of a “Wait, who is that?” moment came when photos surfaced this summer of Tilda Swinton on the set of Judd Apatow's star-studded comedy, which will hit theaters next July. Swinton's always been a bit of a chameleon, and was as equally as unrecognizable as an old woman in March's “Grand Budapest Hotel.” (Everett/Getty)

"Sin City: A Dame to Kill For" could be a case study in how and how not to render your actors unrecognizable: First there's Mickey Rourke as the lumbering Marv, looking decidedly un-Rourke-ish under loads of makeup and heavy prosethetics.
