Untitled Time Machine sequel

Following the release of The Time Machine in 1960, director George Pal wanted to make a sequel.

Plot
The plot is mostly unknown. The possible story would focus on George restoring mankind.

Cast
Rod Taylor as H. George. Wells.

Why It Was Cancelled

 * 1) MGM rejected several scripts that was submitted.
 * 2) It seems likely that MGM didn't want a sequel since the original novel doesn't have a follow up and the first movie doesn't have a sequel based ending.

Results

 * The first movie is stand-alone.
 * George Pal would make a book that serves as a follow-up to the film.
 * George Pal passed away in 1980.
 * A documentary was made in the 1990s, titled The Time Machine: Journey Back, which has a mini-sequel at the end.
