James Cameron's Sanctum – review

This cave-diving drama-cum-disaster-movie is not actually written or directed by James Cameron, but he is its executive producer, and it very much bears his stamp. He has a well-attested fascination with the gung-ho world of deep-water exploration. Richard Roxburgh plays Frank, an experienced caver leading a team exploring a huge cave network in Papua New Guinea; Ioan Gruffudd plays Carl, the blowhard business mogul who's bankrolling the project. Disaster strikes and the team start dying one by one. It's a reasonable film, unpretentious in its way. There is one moment of unintended comedy when Victoria, played by Alice Parkinson, rashly insists on doing a dive without a wetsuit, risking hypothermia: this means she has to strip shiveringly down to her underwear in one scene. Something there for the Keys/Gray demographic.
