Quest for Love is a 1971 British romantic science fiction drama film directed by Ralph Thomas and starring Joan Collins, Tom Bell and Denholm Elliott.

The demonstration goes wrong and Colin (with his same memories) finds himself in a parallel universe with significant differences from our own: John F. Kennedy is Secretary General of a still-existent League of Nations, Leslie Howard did not die in the Second World War because it never happened, and no one ever succeeded in climbing to the peak of Mount Everest.

Tom Bell nicely registers the hero's incredulous perplexity as he discovers that Everest is still unconquered and that a taxi fare to Watford is twelve shillings (60p or 1500 yen), getting understandably if obnoxiously drunk at a first-night party and blundering into a series of disastrous faux pas with former mistresses whom he does not recognise.

But after this often funny introductory half-hour, the film slows down to dwell on pedantic dialogue and loud, emphatic music, a death scene on a piano stool and a ludicrous chase around Heathrow airport.

"[7] TV Guide called the film "an unusual science fiction tale that doesn't completely work but does hold interest...The story gets complicated, but the direction juggles the separate worlds without much trouble.

Bell is on the right note from the beginning of the film, never overplaying his hand ... Collins, whom too many people know only from TV's Dynasty, is simply wonderful here, creating a fully-dimensional character.
