Three Bites of the Apple is a 1967 American romantic comedy film directed by Alvin Ganzer.
An unlikely night of successful casino gambling on the Italian Riviera leaves him wealthy but in a quandary.
Carla Moretti, a beautiful bystander at the casino, volunteers to help, but in fact intends to fleece Thrumm with the help of her ex-husband.
As summarized by Michael Betzold, the "lightweight comedy" turns into a "long car chase with many comic diversions and a lot of Alpine scenery".
