A-list actor looks totally unrecognizable with white beard and Christmas sweater in NYC – can you guess who he is?

AN A-LIST actor looked totally unrecognizable as he was spotted in New York City with a white beard and wearing a Christmas sweater.

The 77-year-old was on set for his latest holiday movie - his first festive flick in nearly three decades.

As well as the facial hair and Christmas attire, the star was in character with facial prosthetics.

Arnold Schwarzenegger was filming scenes for The Man With The Bag, in which he stars alongside Alan Ritchson.

While full details of the new movie have yet to be revealed, an official summary reads: "When Santa’s magic bag is stolen, he turns to his naughty list to find Vance, a former thief, to help him get it back.

"Along with his daughter, Santa, and a group of misfit elves, Vance will have to pull off the greatest heist of his life to save Christmas."

The former governor of California plays Santa Claus in the film while Smallville star Alan, 42, takes on the character of Vance.

Arnold starred in the 1996 Christmas classic Jingle All The Way.

He recently became a grandfather for the third time after his daughter Katherine, 35, welcomed son Ford Fitzgerald Schwarzenegger Pratt with actor husband Chris Pratt in November.

The couple are also parents to Lyla Maria, four, and Eloise Christina, two.

Chris also has a 12-year-old son, Jack, with his ex-wife, Anna Faris.

Arnold previously opened up about life as a grandfather, describing it as the "easiest thing".

During a past appearance on Jimmy Kimmel Live, he said: "I’ll tell you one thing that it is the easiest thing to be a grandfather.

"Because they come over to the house, you play with Lyla for around an hour or two.

"I put her on the horse, I put her with the dog, I play with the dog, and after two hours, they leave. Over."

Arnold has a Hollywood career spanning more than 50 years and is perhaps best known for starring in The Terminator franchise.
