Let's make this birthday one to remember.

51 years old (Born on August 05, 1973)

Happy Birthday to the incredible Paul Kasey—actor extraordinaire, master of monsters, and the only man who can convincingly terrify us one minute and charm us completely the next! Whether you're creeping around as a Cyberman in Doctor Who or lurking mysteriously through Torchwood's shadows, you've always managed to make sci-fi fans both scream and smile.

Here's hoping your birthday is filled with fewer prosthetics than usual (unless that's your thing!) and more cake than an Ood could handle. Thanks for bringing so many unforgettable creatures to life; may this year bring you even greater adventures—and perhaps a monster-free day off!
