Of all the Cop shows of the seventies I liked, and there were a few, none have held quite the same place in the public's - or my - heart as Columbo.
There were in fact two actors who played Columbo before Peter Falk, I'll leave it to your ability to Google to find out who they were, but it was Peter Falk who made the role his own. So much so that 'The Columbo Question' is now an actual expression used in law, politics and media.
For those not familiar with the shows Columbo would ramble through a series of questions appearing to be slightly confused and baffled, often seemingly convinced by the murderer's innocent explanation of potentially incriminating evidence, his questions deliberately leaving an escape route and then 'Just one more thing...'
The real purpose of the questioning when the murderer is off guard and thinks s/he has navigated to storm.
Of course these days everything gets rebooted and, almost equally, of course roles don't necessarily go to someone of the same race or gender as the orignal actor.
If the rumours are to be believed, and I have my doubts, the two actors in the running for Columbo 2 are Mark Ruffalo of Avengers/Huk fame and Natasha Lyonne most famous for Orange is the New Black.
So who should it be?
You might as well ask who should take the role of Rick Blaine in a remake of Casablanca.
You don't tug on Superman's cape, you don't spit into the wind and you don't remake Columbo - that's Peter Falk's role and if you want to make a show inspired by it, celebrating it or paying homage to it that's a fine thing to do but Peter Falk IS Columbo. Accept no substitutes before or after he took the role.
