Avventure di un uomo invisibile

John Carpenter has stated that this is his least favorite of all the films he's directed, and is the film he "hates thinking about the most". One reason was because of the constant studio interference that didn't allow Carpenter much creative freedom. Carpenter also called Chevy Chase "a director's worst nightmare" and "nearly impossible to direct", also saying the same about Daryl Hannah. According to Carpenter, Chase would complain non-stop about the film's tone and hated wearing the special effects, often prematurely removing his makeup and ruining hours of filming. At one point, Carpenter broke a clipboard in half over his knee in a fit of rage when Chase removed his makeup mid-take. Carpenter said that Chase and Hannah were "immune to any punishment from the studio, and they knew it, so they walked over me and everyone else on set and essentially told us we'd be replaced if we had any problem with them...it was like working with your boss's snooty children who would tattle on you if you didn't bend to their every will." Despite this, Carpenter ended up bonding and seeking comfort in Sam Neill over the troubling production and the two became close friends, with Neill agreeing to work with Carpenter again on Il seme della follia (1994).

An invisible man would be blind, the only way to see is for light to reflect off the back of the retina. If the retina is invisible the light would pass through. In the book, it was theorized that the energy particles that make up his body interact differently with visible light allowing him to see.

Over the first minute or so of the end credits we see Nick skiing in snowy mountains, his head and face covered with a hat, goggles and scarf. He comes to a stop outside a large cabin. Alice comes out, evidently pregnant. Nick lifts his goggles and pulls the scarf down from around his face, but of course he is still invisible. Alice kisses him, and takes his gloved hand and holds it to her belly, so he can feel the baby kicking...

UK cinema and video versions were edited to remove 'fuck you' in order for the film to receive a PG rating. The 2003 DVD was uncut and upgraded to a 12 certificate.
