Unlike the original trilogy, which was largely shot on location, On Stranger Tides has used Hawaii as a Caribbean stand-in (we can't imagine the cast and crew were too devastated by that), as well as taking a jaunt to these shores for some filming in Greenwich Docks and Pinewood Studios.

Depp made headlines around the world when he visited a local school while shooting in Greenwich.

Making the planet's female population swoon even more heartily, Depp responded to a school kid's letter asking him to come in to help stage a mutiny against the teachers.

Arriving unannounced in full Jack Sparrow costume, he turned up for an impromptu assembly.

Depp's generosity and obvious passion for the character seemed to charm even the most Pirates-cynical people out there.

And the film looks to be making effective use of its locations.

The exotic locales are visually in keeping with earlier entries in the franchise, and the London-set action has a suitably convincing period sheen.

It should be refreshing to see Sparrow outside of the holiday brochure locales.
