Bruce Greenwood
Bruce Greenwood is a Canadian actor who is very good at playing down-to-earth, normal, everyday characters - characters you could conceivably bump into at the mall or meet in a bar.
It's rather ironic, then, that his most famous roles involve him in positions of tremendous power - Captain/Admiral Chris Pike in Star Trek, John F. Kennedy in Thirteen Days, and the unnamed President in National Treasure: Book of Secrets.
The quality of his films is hit-or-miss - he's starred in everything from the Lifetime-esque Harlequin TV movie Treacherous Beauties to the charming indie romance The Republic of Love. However, Greenwood is consistently real and wonderful in whatever role he plays - he is frequently the only watchable thing in some of his lesser-quality films.
He also starred in the UPN series Nowhere Man, and has guest-starred in various television series, including St. Elsewhere.
Oh, and his voice is very, very sexy.
May cause Hey, It's That Guy! moments, as you may have seen him in Eight Below, Rules of Engagement, Ararat, Racing Stripes, and Double Jeopardy, among others. He also does animated voiceovers; he plays Batman in both the film Batman: Under the Red Hood and the animated series Young Justice.
