We all know Peter Falk had a fake eye. But did Columbo also have a fake eye, or did Falk’s fake eye play the part of a real one?

Columbo’s unsettling, uneven-eyed stare was due to Falk’s glass eye in the right eye socket. It remained a mystery for 25 years whether the character had one as well, until 1997’s “Columbo: A Trace of Murder”, whereupon asking another character to revisit the crime scene with him he jokes: “You know, three eyes are better than one.”
