As long as they don't have him playing a German soldier - I don't think I could handle listening to him massacre a German accent (and he would - accents really aren't his strong suit!)
You know, I was thinking about films this morning and got to wondering why they have never (in the US) done a drama about an actor. Not a crazy actor or a bad actor or a weird actor - just an actor. Someone who has some ups and downs, some measure of success, some of failure - a look at their professional life and their personal life, etc, etc. I think it came to mind because I had read an article about the new Colin Firth film "A Single Man" (which looks wonderful, btw).
Has that been done? I could see Sean in a role like that.
