Dana Carvey still wants to pump you up. He and cowriters, including Conan O’Brien and Kevin Nealon, have completed a script for a big-screen version of Hans and Franz — Saturday Night Live‘s bodybuilders — that finds the two in search of their idol, Arnold Schwarzenegger. The twist? ”It’s a musical,” says Carvey. The catch? Arnold hasn’t agreed to costar. ”We’re trying to get him,” says Carvey, ”but he’s a busy man.” Especially since he’ll need to take singing lessons before filming begins. ”We want him to do the movie’s theme song, ‘No One Knows What a Muscle Man Feels,”’ says Carvey.
