Ali Wong says she and Steven Yeun broke out into hives after filming their upcoming Netflix series, "Beef."

Audiences at South by Southwest watched the world premiere of "Beef" on Saturday, followed by a Q&A with Wong and Yeun. The series follows the aftermath of a road rage incident between Danny Cho (Yeun) and Amy Lau (Wong). According to Variety, one audience member asked the pair how they decompressed after filming the rage-filled scenes.

"Our bodies shut down," Yeun said.

"Steven and I both broke out in hives after the show. Mine was on my face. His was all over his body because he's weak like that," Wong said. "It definitely took a toll on us, but we didn't even realize until after the show ended. I mean, I won't even talk about what happened to your elbow."

According to Wong, neither actor anticipated the visceral reaction, Variety reports.

"I don't think we knew that was going to happen," Wong said. "If we knew what we were going to put our bodies and minds through, maybe we wouldn't have said yes, but we're really glad we did."

"Beef" will hit the streaming site on April 6.

South by Southwest kicked off on March 10 and continues until March 19. A number of highly-anticipated films and series debuted at the festival, including "Dungeons & Dragons: Honor Among Thieves," Donald Glover's "Swarm," and "Evil Dead Rise."
