Shocker: Tequila and a children's movie premiere do not mix.
Woody Harrelson appeared on Jimmy Kimmel Live on Monday, Oct. 14 promote his latest project Free Birds, an animated kid's movie, but the conversation was anything but kid-friendly.
In fact, the 52-year-old actor shared without hesitation that he had such a massive hangover at the film's Hollywood premiere on Oct. 13 that he could "barely stand up" on the red carpet.
He told Kimmel, "I think the premiere was at noon and I went to bed at 6:30 or 7:00 a.m."
Doing what, one might ask?
"Having stayed up all night, drinking tequila and playing pool with my brother, which, uh, didn't go well," the actor shared with a chuckle. "And you know, being waken up, like, three and a half hours later was terrible. It was like a betrayal."
Harrelson, who called his red carpet experience "not pretty," employed his more coherent Free Birds costar Owen Wilson to field reporters' questions to help alleviate the load.
"I told him ahead of time, '[You're] doing all the heavy lifting here. I can barely stand up.' "
Wilson responded, "No problem, buddy. Just leave it to me."
Unfortunately for Harrelson, his Wedding Crashers costar chucked questions back at him. "So we'd be in the middle of the interview," the Hunger Games actor said. "And they'd ask him a question and talk for awhile. Then he'd go, 'What do you think, buddy?' " Harrelson shared in his best Wilson impression. "And I'd be like, 'Well, I agree with you.' "
Harrelson dished to Us Weekly that he and Wilson created a scene in the sound booth before they were split up. "We were our own best audience," he shared. "And [director] Jimmy [Hayward] separated us. Not getting enough done I think."
Free Birds hits theaters Nov. 1.
