Actor Tom Hanks did not meet the actors who played the Somali pirates in his new movie Captain Phillips until they filmed their first scene together.

Director Paul Greengrass purposely kept the Forrest Gump star away from the group of men because he did not want them to develop a friendly relationship - and it worked.

Hanks admits when he first met the actors, he was genuinely afraid and his apprehension benefited their scenes together.

He tells U.S. breakfast show Today, "They were the skinniest, most terrifying human beings I'd ever come across."
