Playing Johnny Cash seems to have really gotten under Joaquin Phoenix's skin. The actor, who learned guitar for the role, has been making a record with musician Tim Burgess. "Once he learned guitar, he found that he had quite a lot of demons inside himself that he wanted to expel through music," reveals Tim. But don't hold your breath waiting for the record; Joaquin is apparently a real perfectionist. "All the tracks... were brilliant, but I think he just keeps scrapping everything or redoing everything. I'm sad to say that I think it's one of those records that many never come out, to be honest with you." If it sounds anything like Scarlett Johansson's foray into music, maybe that's a good thing!
