It's Nathan Fillion's birthday and you can't let such an event pass by without taking the time to celebrate the "Castle" star. Though Fillion appeared on many shows, including a regular role on "Two Guys and a Girl," he jumped onto the radar of most as Malcolm Reynolds on Joss Whedon's "Firefly."
The show may have only lasted one short season, but it was enough to give him a permanent place in the pop culture hall of fame. His continuing to work with Whedon on "Buffy the Vampire Slayer" and, of course, "Dr Horrible's Sing-Along Blog," certainly didn't hurt the cause.
Now, with "Castle" going strong, there's no stopping Fillion. So take a moment to bask in his birthday glow with a collection of his best on-screen moments, captured in GIF form.
