The 3-D action-thriller Sanctum follows a team of underwater cave divers on a treacherous expedition to the largest, most beautiful and least accessible cave system on Earth. When a tropical storm forces them deep into the caverns, they must fight raging water, deadly terrain and creeping panic as they search for an unknown escape route to the sea. Master diver Frank McGuire has explored the South Pacific's Esa-ala Caves for months. But when his exit is cut off in a flash flood, Frank's team-including 17-year-old son Josh and financier Carl Hurley are forced to radically alter plans. With dwindling supplies, the crew must navigate an underwater labyrinth to make it out. Soon, they are confronted with the unavoidable question: Can they survive, or will they be trapped forever?

Did You Know?


At one point Richard Roxburgh asked the art department if they could lighten the load of the pack that he has to carry for most of the film. The next morning they presented him with the reduced weight pack, telling him that they'd managed to take 2 kgs off the total weight. Of course, they hadn't bothered doing anything at all but Roxburgh was convinced that they had. See more »


When Victoria lands, gets off the seaplane and walks to the helicopter she is wearing blue jeans and a white pull-over top that has 2-3 buttons at the top like a regular shirt, it has button flaps on the arms for rolling up the sleeves and she has a white bra on underneath. They all get into the helicopter and it appears to take off immediately, but the very next shot of her shows her top has changed to a full button-down shirt, left unbuttoned with a white halter top underneath and a white bra. She could not have changed all those tops with the helicopters seatbelt/shoulder harness on. See more »

26 February 2011 | by (United Kingdom) – See all my reviews

A wonderful film. I had read a couple of reviews on IMDb and decided that it did not sound very good, but how wrong they were! I really don't know much about photography, directors, producers (or even many of the actors) so I always just base my reviews on whether or not I was entertained by the film and this time - three cheers! - I was! It was exciting - The cave scenes gave a claustrophobic feel to it and a couple of times I felt quite panicky myself! The photography was stunning enough to take my breath away. The plot was good enough to hold me enthralled right to the end. (Of course, it was not a particularly original plot but then again very few are and considering the numbers of films being churned out every day we can't be surprised if most of them use and re-use plots.) But this one was very well done. I felt sympathetic to the characters so I did want to know how it all turned out and although bits of it were predictable, it all made perfect sense (another plus for me!). To sum up, here's a film that I watched from start to finish and I enjoyed every bit of it.
