Zac Efron fans were shocked by his appearance in his latest interview, with many claiming he looked unrecognizable.

A clip from Efron's new promotional interview with Entertainment Weekly for his upcoming wrestling movie, "The Iron Claw," showed the 36-year-old actor with his prominent jawline and face transformation.

After the clip was shared Monday on Instagram and X, formerly Twitter, fans immediately flocked to the comments section to express their shock.

"What the hell happened?" one fan wrote under the clip on Instagram.

"Love that mechanical jaw," a second user wrote.

"Wow! He looks soooo different! It doesn't even look like him. Maybe I'm trippin'," another added.

"What happened to his face??" another user commented.

Some compared him to characters like Thanos from "Avengers" and Lord Farquaad from "Shrek."

"He looks like Thanos now," one claimed, while another user commented, "'Shrek' live action? Omg."

Some suggested that "growth hormone has wrecked his jaw/lips," while others claimed that Efron "just likes plastic surgery."

But many others came to Efron's defense, with one pointing out that "Z said that his jaw shattered in an accident, and he had to get it restructured, which is supposedly why it looks different now."

"Y'all, he shattered his jaw 10 years ago," another commented.Other fans said that Efron "still looks hot" and remains "beautiful inside and outside."

Speculation that Efron had plastic surgery on his jaw first surfaced in April 2021 after the actor appeared in a clip promoting an Earth Day special from Bill Nye, with many alleging he looked different in the video. 

Efron addressed the rumors last year during an interview with Men's Health, saying that his looks changed after he fell over at his home and broke his jaw in November 2013.

He explained that his face and jaw muscles had to work extra hard to compensate for his injury, causing them to enlarge.

"The masseters just grew," he told the magazine. "They just got really, really big."

Efron stars in Sean Durkin's new A24 biopic "The Iron Claw" as the legendary Kevin Von Erich, also known as Kevin Adkisson, a professional wrestler who rose to fame in the 1960s.

Also starring Jeremy Allen White and Harris Dickinson, "The Iron Claw" hits theaters on Dec. 22.
