"Stop Me Before I Kill" or "The Full Treatment" is a 1960 film with a screenplay by Val Guest, who also directed.
The story concerns a famous race car driver, Alan Colby (Ronald Lewis), who was involved in a terrible car crash with his wife Denise (Diane Cilento). He is unable to race, and he and Denise go to the south of France on vacation.
Alan goes through swift mood shifts - the slightest word can set off his temper. And he keeps being tempted to strangle his wife - in fact, he nearly does a couple of times.
This, of course, is where one has to suspend belief because why the heck would she stay with someone who has attempted to strangle her and whose temper flares at the drop of a hat? I understand women in abusive situations, but I don't know, my husband trying to kill me takes it to a new level.
A psychiatrist they meet, Dr. David Prade (Claude Dauphin) offers to help. Alan is hesitant, but once back in London, where Prade has also returned, he agrees. At the end of the treatment, he feels that he is cured. He is able to get back on the racing track and has no temptation to hurt Denise.
Right before he is to leave for a race, Alan wakes up and finds that Denise is not there. In fact, all the evidence points to the fact that she has been murdered.
This was a very good story that suffered from an unbalanced script. The film went on too long, and the psychiatric scenes were endless. Diane Cilento is a beautiful and heartfelt Denise, Claude Dauphin is likable, and Ronald Lewis for me lacked subtlety in a difficult role. A good-looking man, in the beginning of the film, he reminded me of David Hasselhoff; fortunately, the resemblance faded somewhat.
Sadly Ronald Lewis committed suicide in 1982, bankrupt and his career in the doldrums.
In other hands and a bigger budget, this could have been an excellent film. However it's worth seeing for the story.
