"I might take it to another level," warns the power behind MTV's Punk'd (for eight years) and E!'s Pop Fiction (since March), talking to Ryan Seacrest on his KIIS-FM radio show Wednesday.
Now that "punk'd" has not only entered the vernacular but made the dictionary, Kutcher, 30, says he was walking down the street the other day when he got an idea for something new to do with it: Punk'd: The Movie.
Kutcher says he has a plan in mind but is keeping it under wraps so as not to spoil anything.
As for the origin of "punk'd," "I made up a word," Kutcher told Seacrest, who noted that Ashton also said he is the "most happyliest" married person on earth.
"My sister calls them Ashton-isms," said Kutcher of the terms he comes up with.
No Costarring with DemiAnd though he and Demi Moore – to whom he is "happyly" married – both appeared, albeit in separate scenes, in 2006's dramatic movie Bobby, Kutcher isn't sure they'd work well as costars, because, he reasons, "so much is made of our personal life in the press, I think people would have a hard time disconnecting from the fact that we're together, married, in love ... and so they would have a hard time believing our characters."
In the meantime, besides promoting his new screen comedy with Diaz", What Happens in Vegas, he's involved in a new project with Tyra Banks, about which he would only say that they are "looking for the most beautiful person in the world."
Applicants who believe they fit the bill may post photos on Kutcher's MySpace Celebrity blog.
