And no one mentioned Somewhere in Time
Maybe because people tend to get it mixed up with
Time After Time?
For the record,
Somewhere in Time is the one where Christopher Reeve goes back in time and falls in love with Jane Seymour. Based on the novel by Richard Matheson.
Time After Time is the one where H. G. Wells pursues Jack the Ripper to modern-day San Francisco and falls in love with Mary Steenburgen. Based on the novel by Karl Alexander.
And then, of course, there's
Time and Again by Jack Finney, but, oddly, nobody has gotten around to filming that yet. Ditto for
Time and Chance by Alan Brennert.
