Sanctum (2011) watch online

Sanctum is a 2011 3D action-thriller film directed by Alister Grierson, and written by John Garvin and Andrew Wight. It stars Richard Roxburgh, Rhys Wakefield, Alice Parkinson, Dan Wyllie, and Ioan Gruffudd. The film was co-presented and executive produced by James Cameron.

The concept was inspired by an incident in 1988 which Wight and other cave divers were trapped in the underwater cave systems of Nullarbor Plain after a storm collapsed the entrance. A co-production between Australia and the United States, with filming occurring in the former, the film uses 3D photography techniques previously used for Cameron's Avatar. Universal Pictures and Relativity Media bought the distribution rights for various territories.

The film was released in Australia on 4 February 2011, and a day later in the United States. Despite receiving generally negative reviews from critics, it was a box office success, grossing $108 million against a $30 million budget. It also received an AACTA Award nomination for Best Visual Effects. Universal Studios Home Entertainment released Sanctum on DVD, Blu-ray Disc, and Blu-ray 3D on 7 June 2011.
