'Black Sea' director on the submarine thriller

'Black Sea' starring Jude Law opens in this theaters this Friday.

It's a story of a crew on board a submarine on a deep treasure hunt - a mission that could cost them their lives.

The suspenseful adventure thriller is directed by Academy Award winner Kevin MacDonald.

MacDonald visited the 6abc studios and tells us things get really tense for the men on board, especially since they are stuck in a submarine.

"There's something tense, suspenseful about being on a submarine. You're surrounded by water, you're in this tiny little tin can. Any little thing that goes wrong, you're all doomed," MacDonald said.
