I checked that movie out again this weekend and it was still pretty weak. You're right, the only scene that was really worth anything was the RZA/GZA/Murray scene. Sometimes a shitty movie really is just a shitty movie.

Coffee & Cigarettes didn't work because the acting was terrible. Of course Iggy Pop can't act. They figured, oh we have a bunch of singers and actors, THIS WILL WORK, but it didn't.

I loved the RZA, GZA, and Billy Murray scene, and I loved Tom Waits, but Iggy was awful and annoying.
