Untitled Time Machine sequel

Following the release of The Time Machine, director George Pal wanted to make a sequel. Several scripts were submitted, but were rejected by MGM.

Plot
Unknown. Probably would have focus on George restoring mankind.

Why It Was Cancelled

 * 1) As mentioned before, MGM rejected several scripts that was submitted.
 * 2) It's seems highly unlikely that a sequel will ever happen. Because 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 a stand alone.
 * George Pal passed away in 1980.
 * A documentary was made in the 1990s, entitled The Time Machine: Journey Back, which has a mini-sequel at the end.
