Godfather I, II, Apocalypse alone make him my #1. Can't top that. Add in Gatsby, Outsiders, Rumblefish and Bram Stoker's Dracula (I tend to brb;jo to crazy Winona Ryder in that one), and he's my clear number one.
I'm not an ET guy, nor am I moved by Indiana Jones movies. Schindler's List and Saving Private Ryan put him up there in my top … whatever. I thank him for his work in those, particularly the latter.
John Hughes - agree with that. Doesn't belong with the greats, but he was a significant producer of entertainment that has stood the test of time, even the teen-aged stuff - Weird Science, Sixteen Candles, etc. - which really define the era and work like documentaries now for those who weren't alive or of-age back then.
Back to Spielberg - gotta thank him, too, for Jaws. Iconic monster movie.
Scorsese - Taxi Driver, Casino, GoNY, Departed, Cape Fear … all very good and among my favorite movies. For me, though, he is Goodfellas, and for that work, I thank him profusely. But, eyebrows too bushy. I mean, what is that? Like, a genetic disorder or something?
