Finally, we've come to the smoking hot "1979 San Francisco riff on a classic time travel story -- but with Jack the Ripper also because that's awesome" of time travel: Time After Time.

Director Nicholas Meyer dives into H.G. Wells' novel The Time Machine, mixes in the story of an 1800s serial killer, takes the whole thing to San Francisco (just like he will with Star Trek in The Undiscovered Country) and tosses in the First Lady of Time Travel, Mary Steenburgen.

Then things get weird, as Time After Time is alternately an adventure story, a fish-out-of-water comedy, and a story about gruesome murders. It's pretty awesome. Although the time travel doesn't make a ton of sense.
