A couple years ago, someone posted here about "enough rope", a 1h movie made in 1960 with a similar plot as prescription murder but different actors (including the one starring columbo), I watched it recently and found it quite interesting, as there were many similarities but also some things that happen differently compared to the episode we're used to, and as I had never seen it before it's still the closest it gets to a new episode for me, and it can be found quite easily online these days.

Anyone saw that? If so, what did you think of it?

I'm afraid I've missed it so far.

Enough Rope is better, Prescription Murder is a padded out version to fill a time slot. The two Columbo characters are similar, in Prescription Murder Peter Falk is not yet the friendly loveable character where things like his coat and his car are guest stars, along with his unseen wife.
