Arnie comes to town.

Arnold Schwarzenegger had some fans worried about his health after he was spotted looking less than usual in New York on Tuesday. However, the star had a good reason for the change in his appearance.

Consternation spread as photos and videos circulated online showing the 77-year-old action star wearing a holiday sweater and sporting a bushy gray beard and longer-than-usual gray hair.

In a video posted on X, Schwarzenegger could be seen walking slowly alongside his bodyguards.

Some people online commented on how much older the Terminator star looked. Multiple reports said fans “aged Schwarzenegger 200 years in two months.”

However, many fans were quick to point out that Arnold changed his appearance due to a new movie he is filming.

In “The Man with the Bag,” the former governor of California plays Santa Claus alongside “Reacher” star Alan Ritchson, 42.

Still, many believed that Schwarzenegger was showing the signs of his age. One person commented that the star was “definitely slowing down.”

“The way he walks suggests his 77 years are catching up with him,” wrote another.

Still others came to Schwarzenegger’s defense.

“He’s 77 years old…and doing better than most his age,” one fan commented.

“He’s getting ready for a movie that’s why he looks like that!” said another.

“The Man with the Bag” follows Santa as he tries to retrieve his stolen magic bag, even going so far as to enlist the help of a former thief in his quest to save Christmas.

The film will be Schwarzenegger’s first film since 2019’s Terminator: Dark Fate. It will also be his first holiday film since his appearance in 1996’s “Jingle All The Way.”

The actor shared his excitement about “The Man with the Bag” in an Instagram post on Monday.

“Santa Claus is coming to town! “Awesome filming The Man with the Bag with @alanritchson,” Schwarzenegger captioned a photo of him on set alongside Ritchson.

The star praised the film’s director, Adam Shankman, as “one of the funniest directors I’ve ever worked with.”

He also showed NYC some love, writing, “New York City is an amazing host.”

“I can’t wait to share all this Christmas joy with each and every one of you,” he concluded.

Shankman, 60, also posted about the film on Instagram. “Let the reindeer games begin,” he wrote alongside a photo of him, Schwarzenegger and Ritchson.
