As predicted, he finally did it. 

After four acting nominations and four loses, Leonardo DiCaprio has won a Best Actor Oscar for his role as fur trapper Hugh Glass in the frontier thriller "The Revenant." 

The 41-year-old was first nominated 20 years ago for his supporting role in "What's Eating Gilbert Grape.” He later reached true heartthrob status in “Romeo + Juliet” and “Titanic.” But did enter into Oscar contention again in 2005, 2007 and 2014 for “The Aviator,” “Blood Diamond,” and “The Wolf of Wall Street.”

Though the argument has been made that DiCaprio shouldn’t win his first Oscar for "The Revenant," like or not, the actor, to some, got his due, for a physically gruelling film. 

After thanking those who helped him through his career and friends and family, the actor in his acceptance speech, decided to use his win to take a political stand — citing man’s relationship with the natural world, which was what making the film was about, he said.

"Climate change is real, it is happening right now," he said, ending his speech on this note: "Let us not take this planet for granted, I do not take this night for granted."

He may not take this night for granted, but be sure to celebrate the win Leo-style with these moments from his acting through the years.
