Watch the 2018 Oscars livestream

ABC News is on the red carpet before the ceremony begins.

— -- At 8 p.m. ET, the Academy Awards will air live on ABC, but before that, there's plenty to watch!

ABC News will be streaming live from the red carpet outside Dolby Theatre in Hollywood, California, beginning at 4:30 p.m. ET, and all of the action can be seen here.

"It's an awards show for people who have been dreaming about maybe winning an Oscar for their whole lives," he told ABC News. "And the last thing I want to do is ruin that for someone who is, you know, nominated for, you know, best leading actress or best supporting or best director or cinematographer, or whatever, by making it unpleasant."

"I'm not going to ... stop any bad behavior with my jokes," he added.
