Bruce Willis Jokes That He's Going 'Under the Dome' (VIDEO)

Is Bruce Willis finally returning to the medium that made him famous? Willis got his start on "Moonlighting" before transitioning into a bona fide movie star with the "Die Hard" series of films. He dropped by "Late Show with David Letterman," where he joked that he was returning to the small screen as a guest star on the CBS summer hit "Under the Dome."

He even brought a clip of his "appearance." But, unlike most of the characters, Willis isn't under the dome. The narrator explains: "Special appearance by Bruce Willis as the guy who lives right next door to the dome.”

“I’m not in the dome! This is the line, right here, by my house! ... My watermelons!” Willis exclaims in the clip. Okay, it was just a joke, but it was a pretty funny one. His poor watermelons sliced in half like that cow!

"Under the Dome" seems to be doing fine without Willis' star power. The show debuted as the second-highest-rated drama premiere of the entire season, and that impressive viewership jumped to nearly 18 million total viewers when seven days of DVR viewing was added.

As for Willis, he's still going strong on the big screen. Up next is "Red 2," the sequel to the 2010 action/comedy hit, coming to theaters on Friday. Catch "Late Show with David Letterman" every weeknight at 11:35 p.m. ET on CBS.
