The 10 Best Moments from the 2015 Oscars

From the second we saw the first star hit the red carpet at Sunday night's Oscars, we knew it was going to be a night to remember. From the fashion to the awards to the performances and speeches, the 2015 Academy Awards did not disappoint. Read on for our 10 favorite moments of the night:

1. It's safe to say that the Oscars may be our favorite show this awards season as far as fashion goes. From Lupita Nyong'o's jaw-dropping pearl-encrusted custom Calvin Klein gown to Lady Gaga's bright red elbow-length gloves, the ensembles on this year's red carpet had our eyes glued to the TV.

2. Host Neil Patrick Harris's Oscar performance was legendary, right from the very beginning when he opened the awards show with a star-studded performance that included appearances by Anna Kendrick and Jack Black.

3. While we expect quite a few outfit changes from the host, one particular NPH ensemble left us speechless. Continuing his hilarious streak, Harris came on stage at one point wearing nothing but a pair of boxers.

4. Patricia Arquette’s emotional acceptance speech for the best supporting actress Oscar, where the actress demanded equal wages and equal rights for women, had attendees including Meryl Streep and Jennifer Lopez cheering from their seats.

5. Following the in memoriam portion of the evening, Jennifer Hudson took the stage to sing a rendition of "I Can't Let Go."

6. John Legend and Common took the stage to perform "Glory," the original song they recorded for the film Selma, which moved attendees including David Oyelowo (who portrayed Martin Luther King Jr. in the movie) to tears.

7. Idina Menzel poked a little fun at John Travolta's 2014 flub of her name before the two presented the award for best original song, which went to Legend and Common.

8. In honor of The Sound of Music’s 50th anniversary, Lady Gaga performed a tribute of songs from the film on stage. Afterwards, Julie Andrews surprised the audience when she took the stage to present the Oscar for best original score.

9. No surprises here—Eddie Redmayne and Julianne Moore won again. Redmayne took home the Oscar for best actor in a lead role for The Theory of Everything, while Moore took home best actress in a lead role for Still Alice.

10. The cast of Birdman closed out the evening when the film won the most coveted award of the night, best picture.
