James Cameron recently took a trip to "another world" — a seven-mile journey to the bottom of the Mariana Trench — and he was the first person to ever do so solo. Of course, it's not his first go-round with deep sea diving. He also researched the underwater grave of the Titanic after producing the feature film, which coincidentally hits theaters again today in 3D. If you've got a passion for underwater mysteries like James Cameron, get into the mood with some of these films that explore the darkness of the deep, no wet suit required.
