6. Boogie Nights (1997)
Paul Thomas Anderson made this unforgettable film about the life and times of a porn sensation. And we want to see Dirk Diggler (Mark Wahlberg) and his buddies again, for sure.
With the whole shebang returning -- terrific performances by Burt Reynolds, Heather Graham, Don Cheadle, Julianne Moore -- the sequel can move out of adult entertainment into regular Hollywood movie production, which is just as smutty, if not more.
Buck Swope (Cheadle) in a serious dramatic role? Rollergirl (Graham) as an A-lister? Man, this is just begging to be made.
