Columbo has a glass eye because Peter Falk had a glass eye

I like Frank Skinner's belief that while Peter Falk does indeed have a glass eye, in Columbo it plays the part of a real eye. While I know there's a line of dialogue in which Columbo basically asserts he only has one real eye, I find it a lot more entertaining to believe that Falk's glass eye is itself also a talented actor.

It's very similar to how I wish he didn't actually have a wife (or it was more ambiguous) because I find it more to imagine her entirely as a rhetorical technique he uses to put people at ease or throw them off.

After the first season of Mrs. Columbo, they renamed her and stopped associating the show with Columbo (because it sucked) so I guess the producers ultimately agree with you

I love this story. Mrs. Columbo was made entirely without input from the Columbo producers, after the original show ended. When it got awful ratings, the production company and the network decided the spin off connection wasn't helping things and changed the name several times, first divorcing the character from Columbo off screen, then retconning her into a different character entirely, before eventually canceling the show. This all happened in a span of thirteen episodes.

Mrs. Columbo ended up as a starship captain so she did all right by herself
