A look at what's out in theaters this weekend

It's a megadose of Jim Carrey in Disney's version of "A Christmas Carol".

He plays not only Ebenezer Scrooge, but also the ghosts of Christmases past, present and future.

This one's uses the next step of animation techniques we saw in "The Polar Express" and comes from the same director, Robert Zemeckis.

The film's rated PG.

George Clooney puts his mental powers to the test in "The Men Who Stare at Goats".

This is a dark comedy based on a supposedly real, top secret wing of the U.S. military that tries to harness paranormal powers as a weapon.

Jeff Bridges plays the unit's founder, Kevin Spacey's a renegade psychic, and Ewan Macgregor's a reporter investigating the unit.

It's rated R.

Is a life worth a million dollars?

That's the question facing Cameron Diaz and James Marsden in "The Box".

A mysterious man played by Frank Langella presents the struggling couple with a box that contains a button.

If they press it, they'll receive a million dollars, but simultaneously, it'll take the life of someone they don't know.

They have 24 hours to make the choice.

"The Box" is rated PG-13.

Alien encounters provide the basis for the thriller "The Fourth Kind".

That title is also the description for reports of human abduction by aliens.

Milla Jovovich stars as a psychologist studying victims of trauma in Alaska when she stumbles upon evidence indicating that trauma may have been alien abduction.

"The Fourth Kind" is rated PG-13.
