14. 'Bill and Ted's Excellent Adventure' (1989)
There are many other goofy time-machine journeys through the past, from A Connecticut Yankee in King Arthur's Court to Mr. Peabody & Sherman; none of those, however, have brilliantly slack-jawed performances by Alex Winter and Keanu Reeves. The premise: Two SoCal teens need to locate famous figures of Western civilization so they won't fail history and their band, the Wyld Stallyns, can stay together and become the musical foundation of a future utopia. The most inspirational moment comes when Ted (Reeves) philosophizes with Socrates by quoting Kansas: "All we are is dust in the wind, dude."
