LOS ANGELES, Feb. 28 -- After six nominations, 41-year-old Leonardo DiCaprio finally took home his first Oscar on Sunday night for his role in "The Revenant."

DiCaprio got his first nomination nearly two decades ago at age 22 for "What's Eating Gilbert Grape."

He was nominated as the best actor in leading role for five times totally, including this year.

He was also nominated as a producer for "The Wolf of Wall Street" at the 86th Academy Awards Ceremony.

An ABC News online report said that "To play an 1820s fur trapper, DiCaprio endured subzero temperatures, sat in makeup for five hours to get 47 different prosthetics, shot an intricate stunt sequence involving a bear attack during a torrential rainstorm, ate raw bison liver and lived with a long, scraggly beard for a year and a half. No other best actor nominee can say that."

DiCaprio also received Golden Globe, Screen Actors Guild and BAFTA awards this year.
