Welcome to the Oscars - and a Likely Heavy Dose of Politics and Controversy

The annual awards ceremony knows politics only too well.

Television viewers, brace yourselves for Sunday night’s Oscars ceremony, which promises to be a bumpy ride for supporters of President Trump.

So far, the Hollywood awards season has been chock-full of criticism against the new president’s actions and rhetoric.

Notably, there was Meryl Streep’s takedown of Trump for mocking a disabled reporter — an act he denies, but had been previously captured by news cameras — and his angry Twitter response, calling her an "overrated" actress.

Though social media — and every big entertainment award ceremony of the new  year — has have been full of celebrity bashes against the White House's newest occupant, the Oscars are no stranger to controversy or the just plain curious.

Here are some examples from the Motion Picture Academy’s history:

Marlon Brando’s 1973 Snub

Instead of showing up to collect his Best Actor award for “The Godfather,” the reclusive and eccentric celeb sent Native American activist Sacheen Littlefeather instead, who refused the Oscar on his behalf. The Academy responded by banning recipients from sending proxies to the microphone.

That Naked Man Behind David Niven in 1974

There was the British actor, minding his own business and hosting the Oscars, when from behind the curtain ran a man in his birthday suit, flashing the peace sign, as well as himself. The practice of “streaking,” (think of it as the granddaddy of the Ice Bucket Challenge) was in full swing at the time.

Niven didn’t miss a beat. “Isn’t it fascinating to think that’s probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings?”

Vanessa Redgrave’s 1978 “Zionist Hoodlums” Speech

The actress was already in public hot water, for producing a documentary sympathetic to the Palestine Liberation Organization, when she won the Best Supporting Actress statuette for "Julia." Things got worse when she accepted the award and referred to protesters outside the theater as "a bunch of Zionist hoodlums." She was booed amid scant applause.

Susan Sarandon and Tim Robbins Get Banned from the Oscars in 1993

The actors, who were living together at the time, were there to present the Best Editing Oscar. But they kicked off their presentation by noting 266 Haitians who were being held at Guantanamo Bay because they were HIV-positive.

“On their behalf, and on behalf of all the people living with HIV in this country, we would like to ask our governing officials in Washington to admit that HIV is not a crime,” said Sarandon. The show’s producer, Gil Cates, banned them as presenters, but the injunction didn’t stick.

Michael Moore Takes On George W. Bush and Gets Booed in 2003

In his acceptance speech for Best Documentary, the maker of “Bowling for Columbine” dropped a bomb on then-President George W. Bush, just days after the U.S. invaded Iraq.

“We live in the time where we have fictitious election results that elect a fictitious president,” Moore said, referring the 2000 presidential contest that was ultimately decided by a U.S. Supreme Court decision.

“We live in a time where we have a man sending us to war for fictitious reasons... Shame on you, Mr. Bush!” His remarks were jeered in the audience and backstage.

The Oscars will be broadcast live at 7 p.m. EST on ABC. Check local listings.
