AceShowbiz - A screening of "A Complete Unknown" in the United Kingdom was starrier with the presence of an A-list action movie star. Tom Cruise made a surprise appearance at the screening of the Bob Dylan biopic on Tuesday, December 17.

In photos circulating online on Wednesday, the "Mission: Impossible" star was seen shaking hands with Timothee Chalamet, who plays the legendary singer in the biopic. The two also posed together, pointing at each other as Cruise had one hand over Chalamet's shoulder.

Cruise and Chalamet were also joined by other cast members, including Monica Barbaro and Elle Fanning, as well as director James Mangold as they took a group photo. The "Top Gun: Maverick" actor was seen posing with Mangold in another shot, putting one hand over the director's chest as they wrapped their hands around each other's shoulder.

For the event, Cruise opted for a semi-formal look in a blue button-up shirt topped with a black jacket and blue jeans. He completed his ensemble with black shoes.

Chalamet, meanwhile, went more casual in a white-and-blue stripped shirt with black skinny pants and black shoes. He sported thin mustache and accessorized with a gold bracelet.

"A Complete Unknown" is based on the 2015 book "Dylan Goes Electric!" by Elijah Wald. According to the official synopsis, "Set in the influential New York music scene of the early 60s, 'A Complete Unknown' follows 19-year-old Minnesota musician Bob Dylan’s (Timothee Chalamet) meteoric rise as a folk singer to concert halls and the top of the charts - his songs and mystique becoming a worldwide sensation - culminating in his groundbreaking electric rock and roll performance at the Newport Folk Festival in 1965."

The movie also stars Edward Norton, Boyd Holbrook, Dan Fogler, Norbert Leo Butz and Scoot McNairy. The biographical drama will open in theaters across the U.S. on December 25.
