Matt Damon Kidnaps Jimmy Kimmel Ahead of Long-Awaited 'Live!' Appearance (Video)

The Oscar winner has spent years getting teased by the "Live!" host; on Thursday, he will make him pay.

UPDATE: Matt Damon Takes Over 'Jimmy Kimmel Sucks'

After years of "running out of time," an onscreen fight and a bit of adultery, Matt Damon is finally going to be a full-fledged guest on Jimmy Kimmel Live!

It just might be an episode sans Jimmy Kimmel.

In the early, lean years of his show, Kimmel began signing off the air with a mea culpa, saying, "Apologies to Matt Damon, we ran out of time" -- the joke being, of course, that no guest that he had on air possessed the star power of Damon. Years later, Damon got in on the joke, making a massively viral video with Kimmel's then-girlfriend Sarah Silverman, called "I'm F------ Matt Damon" in 2008. Kimmel and Damon even had an onscreen fight when he "bumped" him at the end of a show.

Now, Damon is joining Kimmel for a real, live episode -- and from the looks of this teaser clip, it's going to be quite hostile ... if the show actually gets taped.
