Oh for sure it'd be really difficult to find somebody who could play the role even half as well as Peter Falk, but I don't like to roll over and say it's impossible to recast the role. One big story problem would be his being a cop. Which uhhhh I don't think that'd fly. As bad as police were then, they are so much worse. A man like Columbo just wouldn't last long. He's too good. One cop murders someone, Columbo'd expose him as is his moral obligation, and he'd lose his job.
The mental image of basically the Martin Landau episode but it's Peter Falk hunting down Peter Falk is such a gonzo idea I'm sure Falk would love it. It wouldn't make a lick of sense but DAMN IT it'd be fun!
two peter falks a la landau in double shock is exactly what i had in mind! itd be so campy that i think it would wrap back around and be good. i could probably talk him into it. now i just need a ouija board...
regarding cophood, i've had that talk on twitter a few times. i wrote a little thread on it here.
i imagine a current-day columbo as likely a licensed private investigator, someone who works in tandem with the law but not as part of the police. that way, he'd retain the legal authority and access to resources that he uses to obtain and interpret information, but without being part of the problematic entity that is the modern institution of american policing.
really, they're incompatible. there's no way in hell a police department in the 2020s would let columbo exist, and i don't think a columbo in the 2020s would want to remain a police officer. i mention in that twitter thread that cops were always bastards, but at least back then a cop was just some asshole with a shirt and a revolver, maybe a semiauto pistol or vest if they wanted to really beef it up. nowadays they're armed like combat soldiers with none of the commensurate training.
SWAT gear? carrying an AR? bullying, beating, killing a suspect into compliance? that's not how columbo conducts business.

in terms of a new person inhabiting columbo, as much as i'd like to see it, i am pretty firmly in the camp of it being nearly impossible to do. columbo was as much peter falk as peter falk was columbo. they're two different men obviously, but as i've mentioned before, falk put so much of himself into columbo that it's difficult to divorce the two entities. they're like dr. jeyll and mr. hyde.
i'd be totally down for something else. maybe an animated series, an origin story, a columbo descendent, or even just a series with an inverted mystery and a new character who evokes columbo but isn't by name (last i heard natasha lyonne is working on something like this with rian johnson, the knives out director). we need more new media and less reboot media, anyway.
but my opinion on a modern revival of columbo proper? ech. it really isn't as simple as "mark ruffalo looks like columbo" or "natasha lyonne acts like columbo". i think a project relying on that is doomed to fail.
i cannot overstate how legendary a show 70s columbo is in almost every regard. it's not enough to merely have curly hair or channel peter falk in a performance; that show was such an insanely auspicious coalition of talented moving parts that i think it'd be nearly impossible to recapture that sheer magic. you would have to have a huge budget, a ton of the RIGHT talent, a strong creative vision, and a lot of time to even have a chance of approaching that baseline of quality, which, good luck getting on netflix or amazon prime or whatever.
but even if you managed a big budget, it'd be dicey. hell, the bar was set so high that falk himself mostly failed to clear it when he brought his own series back. that's the real barometer of success potential for me.
that said, if i'm ever proven wrong, and on this i would love to be proven wrong, i'd be extremely impressed with whoever managed it. i'd even have to give them brownie points for merely trying--as long as they don't try any weird CGI necromancy.
