I have respect for any actor who played the murderer alongside Peter Falk in the TV show "Columbo
". I think it requires a putting aside of ego, as the thorn-in-the-flesh
detective plucked away at weaknesses of the character involved. In the episode that Shatner played in, he represented a high-profile TV star who was highly flawed (which came out as Columbo worked his magic on him). And Shatner pulled the character off quite well IMO.
