I haven’t yet found a copy of this film to watch, but
Blondes Prefer Bonds may well
be the first talkie with certain time travel that’s not an adaptation of an earlier story.
In the film, the heroine undergoes a scientific rejuvenation process—something to do with
monkey
glands according to Anthony Bald—that causes her and her husband to return to the time
of their courtship. It’s unclear from the descriptions I’ve found whether the
“return” is a literal return in time (and possibly the first
Young
Again story) or something else.
Please let us know if you run across a copy of this
oddly-titled 21-minute film!
