Birdman, Eddie Redmayne and Julianne Moore are gold at 2015 Oscars

Birdman was the toast of the 87th Oscars on Sunday (22Feb15), earning Best Picture as Eddie Redmayne and Julianne Moore also celebrated big wins at Hollywood's big night.

Birdman filmmaker Alejandro Gonzalez Inarritu was named Best Director, while he also claimed Best Original Screenplay and Emmanuel Lubezki received the Best Cinematography award.

Redmayne couldn't contain his excitement as he collected the Best Actor prize for his Stephen Hawking biopic The Theory of Everything, and Julianne Moore scored Best Actress for Still Alice, while fellow awards season favorites and first-time nominees J.K. Simmons (Whiplash) and Patricia Arquette (Boyhood) walked away with the best supporting acting prizes.

Wes Anderson also had reason to celebrate as The Grand Budapest Hotel, which tied with Birdman for the most nominations with nine nods apiece, scored four titles, including Best Original Score for Alexandre Desplat.

Each of the nominations for Best Original Song were performed, but it was John Legend and Common's powerful rendition of Selma track Glory which left actors David Oyelowo and Chris Pine in tears at Los Angeles' Dolby Theater as the audience gave the musicians a standing ovation. Glory went on to win the category.

Meanwhile, Jennifer Hudson honored the stars lost in the past year by singing I Can't Let Go as part of the In Memoriam segment, and Lady Gaga helped to celebrate the 50th anniversary of Oscar-winning movie The Sound of Music with an impressive medley of hits from the Dame Julie Andrews musical, including Edelweiss, Climb Ev'ry Mountain and the title song.

Ceremony host Neil Patrick Harris also showed off his vocals by opening the 2015 prizegiving with a comedic song and dance number with Anna Kendrick and actor/rocker Jack Black.
