Decent actor but probably as well known as other big stars since he primarily does only supporting roles. However, as what Numbers show, he really knows how to deliver a role.
He mainly plays either a bad guy or a clean honest cop but usually they're both very intense. Movies like "No Way Out" with Kevin Costner, "Gone in Sixty Seconds" with Nicholas Cage are a few movies to watch him for. He always leaves an impact usually and the few movies that really use him well are decent movies.
Reminds me a bit of Charles Bronson type of actor. Usually involved in a lot of action stuff but can be serious when he needs to be.
