Michael Keaton paid tribute to Inarritu saying: "This has been a tremendous experience - this guy is as bold as bold can be. It's just great fun to be here."

I pray we can find and build a government we deserve and I hope Mexican immigrants in this country can be treated with the same dignity as the ones who came before and built this immigrant nation."
Best Actress - Julianne Moore for 'Still Alice'
Crying, Julianne Moore "I read an article that said winning an Oscar could lead to living five years longer. If that's true, I want to thank the Academy, because my husband is younger than me!"
"To my husband Bart, thank you for my life, thank you for giving me a home."

He paid tribute to his 'partner in crime' and co-star Felicity Jones, and his 'ferocious and kind director' James Marsh.
