For once, Jimmy Kimmel found the time to talk to Matt Damon.
The Martian actor finally got to appear as a guest after more than 10 years of being bumped from Jimmy Kimmel Live!'s schedule. Damon first appeared on Monday's episode when he interrupted the late-night host's monologue. "I hesitate to mention this, but Matt Damon has a new movie opening on Friday. It's called The Martian. Matt plays an astronaut who gets stranded on Mars. Poor Mars! They have one person on the whole planet and it's Matt Damon. I don't know how the movie producers managed this, but NASA announced an enormous discovery today regarding Mars. They found water—liquid water—on Mars. We can't even find that in California," Kimmel said. "This is an amazing thing. Scientists have suspected that Mars had water for a long time. Let me show you a photograph that they took from the rover, I think. You can see right here. I mean, it was right there the whole time. It was a whole bottle of Arrowhead. They don't know if the water is drinkable or not. It should be. It could be very salty." As he pointed to the screen, the actor appeared and held a sign that read: "Next on Kimmel – Matt Damon."
