Sean Penn is currently on location filming his latest project, This Must Be The Place. In the movie he plays an aging rocker who has a thing for big hair and red lipstick (as you can see above). Several on set photos have been discovered via ohnotheydidnt of the Oscar winner in full costume and we’ve got them for you below…

In This Must Be The Place, Penn plays a retired musician named Cheyenne who sets out to find his father’s persecutor, an ex-Nazi war criminal now hiding out in the U.S. He’s bored, he’s rich and he’s got nothing better to do so he takes his steel-toed boots and leather jacket with him on the road to find justice. Cheyenne and his father had been estranged for 30-plus years and only in his death has he decided to make things right. Will he take the high road or choose sweet and bloody revenge?

These photos are terrifying. Hopefully, this is the closest we’ll ever get to seeing Penn in full-on drag. Certain things just don’t work for everyone.

This Must Be the Place is scheduled to hit theaters sometime in 2011 and is directed by Paolo Sorrentino, and co-stars Frances McDormand and Harry Dean Stanton.

What do you think of Penn’s rocker look?
