8. 'Bill and Ted's Excellent Adventure' (1989)
Keanu Reeves takes up permanent residence in the stoner-flick Hall of Fame, although not even The Matrix or Point Break took him this far into the zone. As he and his buddy go traveling through time, the blankness all over his face made people marvel at his subtle acting. Maybe it wasn't acting? Whoa!
Stoniest moment: Bill and Ted go back in time to meet Socrates (you know, "So-Crates") and blow his mind by philosophizing over "Dust in the Wind."
