We held a giveaway for the movie Sanctum, Alister Grierson’s upcoming action-thriller. The movie is based on explorer and producer Andrew Wight’s own diving expedition to uncharted cave systems beneath Australia’s Nullarbor Plain.

With that said, Screenhead is happy to announce we have picked the winner for the Sanctum Giveaway that includes a poster!

Samantha is our winner, so enjoy Samantha!

Sanctum is now playing in RealD 3D and IMAX 3D. The movie is rated-R and is being billed as an action-thriller. The cast includes Richard Roxburgh, Rhys Wakefield, Ioan Gruffudd, Alice Parkinson and Dan Wyllie. James Cameron is one of the producers.

The 3D action-thriller 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 (Richard Roxburgh) 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 (Rhys Wakefield) and financier Carl Hurley (Ioan Gruffudd)-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?

Shot on location off the Gold Coast in Queensland, Australia, Sanctum employs 3-D photography techniques Cameron developed to lens Avatar. Designed to operate in extreme environments, the technology used to shoot the action-thriller will bring audiences on a breathless journey across plunging cliffs and into the furthest reaches of our subterranean world.

This is what Samantha won:

I am very happy to help Screenhead host a giveaway for Sanctum! Here’s what we are doing. I know, you will love it because I sure do! First of all, I encourage all of you to check out iJustine’s live underwater interview with James Cameron on the Virgin Mobile LIVE Facebook page.

As you probably know by now, Sanctum is playing in theaters and is the number two movie this weekend so far at the box office.

The giveaway is pretty cool and kind of fun because you get to use your imagination in order to enter the giveaway. To enter the giveaway, you post your name and answer this question: If you were trapped in a cave and had to make one phone call, who would it be to?

We are running this contest until Wednesday, February 9, 2011. At the close of the contest, the winner will be selected at random. They will win a $25 Fandango gift card!

I know this is last minute, but it’s worth a shot to promote on Screenhead; particularly, since James Cameron is a key player in the new 3-D thrill Sanctum. There will be an exclusive live streaming event featuring Academy Award-winning Director James Cameron.

James Cameron is the executive producer of a new 3-D thriller called Sanctum and will be doing a live underwater Q&A session at the Long Beach Aquarium Thursday, February 3, 2011 at 9:00AM (PST).

This live event and its archive will be available exclusively from the Virgin Mobile LIVE Facebook page. Viewers can submit questions to James Cameron via Twitter using the hashtag #virginmobilelive.

The Q&A session offers you an opportunity to send in questions for Mr. Cameron, which will be pre-selected. For the questions that are ultimately chosen and responded to they will send autographed prizing and tickets to see Sanctum.

I am really excited about this unique experience for moviegoers. I hope your questions get picked and you win some awesome prizes.
