Eli Hayes’s review published on Letterboxd:
Just a few TIDBITS of trivia:
The MPAA told Lynch that the version of Wild at Heart screened at Cannes would receive an X rating in North America unless cuts were made, as the NC-17 was not in effect in 1990, at the time of the film's release. The director was contractually obligated to deliver an R-rated film. He made one change in the scene where a character shoots his own head off with a shotgun. Gun smoke was added to tone down the blood and hide the removal of the character's head from his body. Foreign prints were not affected. The Region 1 DVD and Blu-rays contain the toned-down version of the shotgun scene.
Sherilyn Fenn's accident scene came from David Lynch's impression of Fenn as a porcelain doll, and from the idea of seeing a porcelain doll breaking. He kept telling her about that, and that's how the scene was born. Lynch said of the scene, "I just pictured her being able to do this. She's like a broken china doll." Lynch got the same inspiration for the car accident scene in Mulholland Drive (2001). His direction to actress Laura Harring was to act like a broken porcelain doll.
The snakeskin jacket Sailor wears in the film was actually Nicolas Cage's own. Cage asked director David Lynch if he could wear the jacket in the film, as a tribute to Marlon Brando's role in The Fugitive Kind (1960). After filming was completed, Cage gave his jacket to Laura Dern. (On a side note, "The Fugitive Kind" was based on the play, "Orpheus Descending," by Diane Ladd's cousin, Tennessee Williams. Laura Dern's parents, Diane Ladd and Bruce Dern, met while appearing in a 1961 stage production of "Orpheus Descending.")
During filming, Laura Dern passed out when David Lynch asked her to smoke four cigarettes at once in one deep inhalation. When she came to, she saw a worried Lynch standing above her asking: "Tidbit! Are you alright?"
