Tom Cruise trailer released

Tom Cruise's personal life may be in upheaval but it was business as usual for the studio promoting his next movie.

Paramount Pictures has released the trailer for Tom's crime drama Jack Reacher, which opens on December 21.

The trailer launched on his 50th birthday, along with the debut of The Amazing Spider-Man.

The start of the movie's marketing campaign coincides with the break-up of Tom's marriage to Katie Holmes, who filed for divorce last week.

The divorce has brought fresh scrutiny to his ties to Scientology. His beliefs played a role in Paramount's split with the actor in 2006 over his discussion of his religion and his erratic behaviour regarding his romance with Katie.

Paramount has since made up with Tom, releasing his blockbuster Mission: Impossible: Ghost Protocol to a 690 million-dollar (£442 million) worldwide haul.

"Tom is a huge movie star for the right reason. He's a very talented actor whose movies have entertained millions of fans," Paramount said in a statement.

"His ability to make a great movie, as we saw with the most recent instalment in the Mission: Impossible franchise - the most successful of the series to date - is the thing that moviegoers remember above all else."

In Jack Reacher, adapted from a novel by Lee Child, Tom plays an ex-military investigator caught up in the case of a sniper accused of killing five people.
