Wow Clarissa, that Charlie Rose clip sure brings back memories!
I found the link for that somewhere on the net right after I'd seen the film (1 and a half years ago!) and it was my first "meeting" with Heath as himself talking about Ennis at length (ie. other than in 2-second type mini-clips). I couldn't believe my eyes - that this extremely fidgety and nervous guy, seemingly so uncomfortable in the spotlight, had created and breathed magnificent life into restrained, careful Ennis....!!! My admiration for him as an actor was very high, but at that point it rocketed completely into orbit and has stayed there since!
