Director Damien Chazelle and Emma Stone on the set of LA LA LAND.Damien Chazelle just made Oscar history with his Best Director win.

The "La La Land" director is the youngest filmmaker to ever win the Academy Award for this category. He was previously nominated for his debut feature, the Oscar-winning "Whiplash," in the Best Adapted Screenplay category. (The film was based on a short he directed).

Chazelle was long favored to take home the award, after previously winning the Directors Guild Award The four other filmmakers competing for Oscar were: Denis Villeneuve ("Arrival"), Mel Gibson ("Hacksaw Ridge"), Kenneth Lonergan ("Manchester by the Sea"), and Barry Jenkins ("Moonlight").

The Oscar-winner spent years pitching "La La Land" to various studios, only to have everyone in town turn it down. Like the aspiring Hollywood dreamers in his film, his persistence paid off on Sunday night.
