Arnold Schwarzenegger sparks concern after transforming into Santa Claus for Christmas movie

Arnold Schwarzenegger had fans concerned about his health after transforming into Santa Claus for his forthcoming Christmas movie, “The Man with the Bag.”

One X user claimed the actor, 77, had “aged 200 years in 2 months” after a video showed Schwarzenegger walking slowly on the NYC set with a full beard and head of gray hair.

“… he probably forgot where he parked his Terminator time machine,” another person commented on the clip.

“Definitely slowing down. Looking older than Trump. Thats wild,” a third wrote.

A fourth person added, “His action movie days are ending.. He’s walking stiff as if he’s in a lot of pain.”

The “Terminator” star — who has experienced recent health scares — is playing Santa in the action-comedy flick produced by Amazon MGM Studios and directed by Adam Shankman.

Schwarzenegger certainly looked the part with his beard and festive Christmas sweater while filming in the Big Apple on Tuesday.

The actor raved about working with Shankman and co-star Alan Ritchson in a post shared on Instagram that same day.

“It is fantastic to be shooting The Man with the Bag with @alanritchson,” Schwarzenegger captioned a snap of himself and Ritchson, who is best known for starring in Prime Video’s “Reacher.”

“Our director @adamshankman is one of the funniest directors I’ve worked with, New York City is an amazing host, working with @amazonmgmstudios is a joy, and I can’t wait to share all of this Christmas cheer with each and every one of you.”

“The Man with the Bag” is a family movie about a quest to save Christmas after Santa’s magic bag is stolen, per Entertainment Weekly.

Schwarzenegger starred in his first holiday movie, “Jingle All the Way,” in 1996.

He played a father on a mission to get his son the Christmas present of his dreams: a Turbo-Man action figure.
