Didn't realize you were such a big fan of solo Gabriel. Knew you like Bolan (particularly the early stuff) but he still seems like kind of a random choice for favorite songwriter (but yeah, you could have put a songwriting team). Can't say he doesn't have a unique style though (especially on those early albums/singles). Did you ever grab that "20th Century Superstar" box set? If not, make sure you do- made me realize that many of Bolan's best songs are non-album rarities.
I guess you're right about actors being inconsistent but so are musicians. By favorite actor, I mean an actor or actress you think elevates most films they appear in and you go out of your way to see films featuring them. Yeah, I've seen some crappy films of Sellers' but I always enjoy watching him. Other actors that fit this category for me are Peter Lorre, Humphrey Bogart, Steve Buscemi, Jack Nicholson, Daniel Day-Lewis, John Goodman and Samuel L. Jackson.
