On the US TV drama series "Columbo", which actor played the murderer more times than anyone else?

UnopposedYogi27101, I am a big fan of the Columbo programmes and it's a shame that in his last few years of life, Peter Falk developed dementia and couldn't remember having appeared in Columbo

Well worth watching The Prisoner - fascinating and ground breaking series

Charlie , yes, you’re correct. These writers always get their facts wrong.

Patrick was amazing as the king in “Braveheart”!

Columbo premiered in 1968, not 1963.
