I prefer the earlier Ronald Colman version myself. I remember reading that Richard Thorpe would run the old version and basically duplicate the scene in the remake. Both are good, with great casts; I just like the old one a bit more.
I prefer the Ronald Coleman version too. Though James Mason could play a really good bad guy, Douglas Fairbanks Jr as Heintzau and Raymond Massey as Black Michael were just wonderful
I have a slight preference for the 1952 version but that’s probably because I saw it first. I’ll grant that David Niven’s Fritz von Tarlenheim easily beats Robert Coote’s.
“Get Smart”’s comedy take on both the 1937 and 1952 films is pretty good, right down to its spoof on the final scenes-

Also, the final 1/3 of Blake Edwards’ “The Great Race” does a funny comedy version of the story as well. And they’re both funnier than the disappointing 1979 spoof with Peter Sellers.
