As a travelog, Three Bites of the Apple has certain merit; as a madcap comedy, its intended goal, it hasn’t. Filmed in Italy and Switzerland, what emerges is an unimaginative piece of film making.The screenplay is based on the flimsiest of premises. David McCallum, a mildmannered tour guide, wins £1,200 in a plush Italian gambling casino; then is faced with the question of how to save it from taxes so he’ll be able to return to his native Britain with any more than a pittance. A pretty young adventuress, Sylva Koscina, out to get the coin for herself, sells him on allowing a ‘friend’ help him in this matter. McCallum seems to stumble through most of his appearance. Koscina has a vapid look but is nice to look at.
