This reviewer seems to think Thomas McDonell is a cross between Keanu Reeves and Depp:
Prom – Movie Review. I haven't seen enough of him to comment. But the review also references DS and says there's not one poor performance in

Thomas McDonell Interview - JustJared.com Exclusive. Who knows? Either he has no idea what he's talking about or they really are filming - something. But who the hell knows what? I wouldn't consider things like the camera tests like the ones that fabric place said were upcoming (before they had to stop supplying info because of the confidentiality agreement they'd signed) to be filming. Filming is actually something that's intended to be in the film...
