Anecdotes

Some of the sound effects used in the time-travel sequences are the same as those used in the TV series Au coeur du temps (1966) and the feature film La Machine à explorer le temps (1960).

Cast members Whit Bissell and John Zaremba co-starred in the TV series Au coeur du temps (1966).

The film takes place in September 1978, on April 10, 1692, on June 30, 1871, on October 14, 2025 and in 802701.

Whit Bissell (Ralph Branly) previously played Walter Kemp in La Machine à explorer le temps (1960).

This is the first adaptation of "The Time Machine" in which the protagonist travels back in time before going forward in time. The same was later true of La Machine à explorer le temps (2002).
