Today is Joss Whedon’s Birthday.

Joss Whedon is one of the most recognizable names in the science fiction and comic book industries, masterminding a number of each genre’s most respected hits. Of course, every fan remembers Whedon’s directorial role in Marvel’s The Avengers. Whedon’s efforts impressed Marvel so much, that the studio made him the cinematic universe’s godfather throughout their Phase Two entries. Whedon filled that role by providing creative consultation, re-writing scripts, launching Marvel’s Agents of S.H.I.E.L.D. television series, and directing this year's Avengers: Age of Ultron.

As Whedon moves to new work outside the Marvel Universe, it’s important to remember his work before the Earth’s Mightiest Heroes. Whedon is also the creator of fan-favorite series including Firefly, Buffy The Vampire Slayer, and Dr. Horrible’s Sing-Along Blog. He also wrote 24 issues (and a giant-sized special) of Marvel’s Astonishing X-Men comic book series, a run that many critics call one of the franchise’s best.

Born in New York City, Whedon turns 51 today. Happy Birthday, Joss Whedon!
