The 2018 Oscars — or the 90th Academy Awards, if you'd prefer — are headed our way on Sunday, March 4, bringing glitz, glamour and maybe even a headline-grabbing mix-up or two, like the 2017 snafu that was the "La La Land"-"Moonlight" debacle (as documented in the photo above). This year, nine films are up for best picture, just one of 24 award categories that will be featured in the Oscars broadcast.

Hollywood's biggest night not only promises a cavalcade of A-list actors and designer dresses, but also tends to mint a selection of memes and awkward moments to delight everyone watching along on social media.

Here's all you need to know to tune in for the show.

What time are the Oscars in 2018? What channel?

The 2018 Oscars start at 8 p.m. March 4 on ABC. The network's pre-show, "Live From the Red Carpet," featuring interviews with nominees and presenters, starts at 6:30 p.m. with hosts Michael Strahan ("Good Morning America") and Wendi McLendon-Covey ("The Goldbergs").

Viewers can also livestream the Oscars at abc.com or through the ABC app, but must sign in with their TV provider to watch.

Ryan Seacrest Oscars: When is E! 'Live from the Red Carpet'?

But maybe you're the type who likes to really revel in the all the Oscars grandeur.

If you're a fashion plate or just interested in what everyone's wearing — and want to get a good look at all the gowns — you can head over to E! starting at 1 p.m. for two hours of "Countdown to the Red Carpet" and, starting at 5 p.m., three hours of "Live From the Red Carpet" with Ryan Seacrest and Giuliana Rancic — that is, if Seacrest is still hosting (E! says that he is).

Seacrest has been making headlines of his own lately after Suzie Hardy, a former E! News stylist, went public with allegations of sexual misconduct and assault. The multi-hyphenate TV host has denied Hardy's claims. Yet some publicists, citing the allegations, reportedly plan to steer their clients away from Seacrest on the red carpet. "Scandal" actress Bellamy Young spoke out against Seacrest hosting the red carpet show at the Oscars, but later apologized to him when she learned that he had already been cleared by an independent investigation at E!

Still, speculation abounds about how stars — including actresses who have shared their own #MeToo stories of sexual harassment, assault and misconduct — will react to Seacrest on the red carpet.

Who are the Oscar nominees?

The Academy Awards always end with the winner for best picture, but there are a lot of categories to cover before then, from best actress to best supporting actress to cinematography, documentary feature, makeup and hairstyling, costume design and film editing.

The nine best picture nominees are "Call Me By Your Name," "Darkest Hour," "Dunkirk," "Get Out," "Lady Bird," "Phantom Thread," "The Post," "The Shape of Water" and "Three Billboards Outside Ebbing, Missouri."

Here are the rest of the 2018 Oscar nominees, including New Jersey's own Meryl Streep ("The Post").

Faye Dunaway and Warren Beatty return for best picture

Faye Dunaway and Warren Beatty, the Oscar presenters partially responsible for last year's mix-up, when "La La Land" was announced as best picture instead of "Moonlight" — the actual winner — are slated to return. Yes, to present the biggest award of the night: best picture. One would think they'll be careful to get it right this time, but could an award go to the wrong person at the 2018 Oscars, considering what happened at last year's show?

PricewaterhouseCoopers, the accounting firm tasked with tabulating the winners of the awards, has instituted several new rules as a precaution after "La La Land" was accidentally named best picture because a partner from the firm handed the wrong envelope to Beatty and Dunaway. The firm told the Associated Press that presenters will now have to confirm they've received the right envelope before they walk onstage to present the award.

There will also be a third partner sitting in the control booth at the awards show who will have a set of winner's envelopes and have all the winners committed to memory. All three balloting partners will have to attend rehearsals for the show. Finally, the two PwC partners who staffed the Oscars last year will not be a part of this year's show.

Who is hosting the Oscars?

Jimmy Kimmel will return to host the Oscars for 2018, even after the "Moonlight" morass he found himself in last year. In a promo for ABC, Kimmel made light of being traumatized by the events of last year's awards show.

"You know I dream about it every night," he says in the video, which features a guest appearance from Beatty. "I can't even open the mail because of, you know, all the envelopes — it just piles up."

Kimmel will be the first person to host the awards show in consecutive years since Billy Crystal in 1997 and 1998.

Update (March 4): Ashley Judd, Annabella Sciorra and Salma Hayek will also present together at the Oscars, as per the Los Angeles Times. All three women have accused fallen Hollywood mogul Harvey Weinstein of sexual misconduct. In Sciorra's case, she accused him of rape.
