Oprah, Tom Hanks and Robert Redford are some of the actors snubbed in the Oscar nominations

SOME actors were a certainty to get a nomination, but clearly someone forgot to tell the Academy. Here are the six biggest snubs from overnight.

IT WAS a rough morning for actors in boats with both Tom Hanks and Robert Redford getting left off this year's list of Oscar nominees for Best Actor.

Here are the New York Post's explanations for five major snubs this morning.

FULL LIST OF THE OSCAR NOMINATIONS

Tom Hanks

Almost everybody agrees he did the best work of his career in Captain Phillips. But with two Best Actor trophies already on his mantle, the actors' branch decided to throw Hanks overboard to make room in a category insanely overloaded with great performances.

Robert Redford

Robert Redford will be lost at this year's Oscars.

This is less understandable - a solo tour de force in a movie (All Is Lost) with virtually no dialogue. Was Redford snubbed because he's not big on gladhanding? Or was he edged out by fellow 77-year-old Bruce Dern in Nebraska?

CATE BLANCHETT NOMINATED FOR AN OSCAR

Emma Thompson

Emma Thompson missed out for her role in "Saving Mr Banks."

Everybody agrees she's great in Saving Mr. Banks, but Disney's attempt to glorify its founder didn't go down even with a barrel full of saccharine. Thompson's "friend'' Meryl Streep plunged the final dagger into the film, and walked away with a nomination for her over-the-top performance in August: Osage County.

Joaquin Phoenix and Oscar Isaac

Joaquin Phoenix as Theodore in the modern day love story film "Her".

It looks like the year's two heavily praised mopey loser performances - in Her and Inside Llewyn Davis respectively - basically cancelled each other out.

Oprah Winfrey

Oprah Winfrey has been snubbed. How dare they!

She's up for a SAG award as best supporting actor for her hammy turn in The Butler on Saturday night. I'm inclined to think her movie and Fruitvale Station got snubbed across the board by Oscar voters mostly as a matter of taste, though some will note what looks like a strict racial quota for nominees in the top categories. There's one black-oriented film (12 Years a Slave) up for Best Picture, and one black nominee for Best Director, Best Actor, Best Supporting Actor and Best Supporting Actress.
