Cher wanted to costar with Cage in Moonstruck because she'd seen him in Peggy Sue Got Married and thought his performance was like "watching a two-hour car accident." According to Cage, he was "flattered."
The scene where he, as Ronny Cammareri, yells out "I lost my hand, I lost my bride!" was inspired by a moment in Fritz Lang's 1927 film Metropolis.
He originally based Ronny's voice and mannerisms on the voice of the Beast in the 1946 version of Beauty and the Beast but ended up scrapping it.
