Let's make this birthday one to remember.

69 years old (Born on December 16, 1955)

Happy Birthday, Xander Berkley! Celebrating another year of the man who stole hearts—and nerve agents—as George Mason on "24." Your heroic (and radioactive!) farewell still makes us tear up... and fear radiation more than ever.

From espionage adventures as Percy Rose in "Nikita," masterfully navigating shadows and spy games, to your chilling portrayal as Sheriff Thomas McAllister—aka Red John—in "The Mentalist," you've kept audiences guessing. Whether hero or villain, your roles always leave an indelible mark. Cheers to continued success and many more characters that thrill, chill, and amaze us all. Have a fantastic day!
