Veteran character actor David Paymer has joined the cast of Jack Ryan for Paramount Pictures and director Kenneth Branagh.

The actor will portray a U.S. diplomat in this action-thriller, which gives us a new origin story for the title character (Chris Pine). The story takes place in Moscow, where Jack Ryan works as a stockbroker for a Russian billionaire. He must put his life on the line when he discovers a threat against the United States designed to wipe out his home country's economic system. Keira Knightley, Kevin Costner, and director Kenneth Branagh also star.
