Let's make this birthday one to remember.

47 years old (Born on October 20, 1977)

Happy Birthday, Samuel Witwer! From terrifying us as Davis "Doomsday" Bloom in Smallville to bravely defending humanity aboard Battlestar Galactica as Lt. Crashdown, your performances always hit stellar proportions—though we admit you gave new meaning to the term 'having a rough day at work.'

May this year bring roles slightly less hazardous than your previous gigs (saving Krypton or battling Cylons is exhausting!), but knowing you, drama is probably inevitable. Keep rocking those intense scenes and mysterious characters; you're proof that good guys can have monstrous side-effects—and still charm everyone along the way.

Wishing you an apocalypse-free celebration!
