Who Better in "An Exercise in Fatality" as the Killer But Robert Conrad? NOBODY
"An Exercise in Fatality" is one of my favorite Columbos. His matched opponent is rich, yes...but not particularly elegant or effete. The guy is a superfit health club chain owner...based pretty much on Jack LaLanne of the time, but younger and more handsome.
Who else but Robert Conrad?
I wonder if, when this story idea was pitched for script, ONLY Robert Conrad's name came up, and he was offered the role first.
As one of the spy show heroes of the 60's, Conrad was muscular and ripped in a way that Robert Vaughn(The Man From UNCLE) and Robert Culp (I Spy) were not. And all three Roberts were Columbo villains. But neither Vaughn nor Culp could have played Milo Janus.
Wracking my mind for a substitute, for some reason I could only come up with Chad Everett(Medical Center). And he wasn't BUFF like Bob Conrad. Burt Reynolds would have been great -- but he was a movie star by '75.
All the shirtless scenes. The push-ups. The boxing bag work-out(Conrad was once a boxer.) Only Conrad.
But wait, there's more: Conrad could really ACT, and Milo Janus' cocky self-confidence and preacher-like belief in fitness("fresh air, exercise, and diet") make him a formidable physical AND mental opponent to Columbo. Conrad looked great and acted mean in "An Exercise in Fatality."
A one of a kind villain.
