Let's make this birthday one to remember.

61 years old (Born on December 20, 1963)

Happy birthday, Joel Gretsch! From navigating extraterrestrials in "Taken" to leading resistance fighters brilliantly against creepy aliens in "V," your characters make battling conspiracy theories and alien invasions surprisingly enjoyable. We still haven't figured out who's scarier: the invading V's or newsroom politics from "The 4400." Either way, you nailed them all with grace!

Here's hoping this year brings even more thrilling roles—because no one else quite masters that distinct blend of charm, courage and mystery like you do on screen. May today be as timelessly entertaining for you as binge-watching our favorite scenes is for us fans. Cheers!
