Le avventure di Errol Flynn

The closing titles mention the term "In like Flynn" but do not give the context. Errol Flynn was able to charm his way into and out of any situation and he had a reputation for being extremely good at it. To be in like Flynn meant to be totally assured of success.

In the 1960s, this expression evolved into an actual movie character, Derek Flint, in the spy spoof films Il nostro agente Flint (1966) and A noi piace Flint (1967).

The Sirocco did not sink on a reef as depicted in the film. In fact, the yacht is still in use today.
