Big chinned twins?

I once saw a very strange black-and-white movie about these old-timey twins with enormous chins - they were boxers. Mr. singular remembers it, too, but neither of our Google-fu powers are strong enough to hunt it down. If there’s a community in the world that could find it, this one is it!

Was it the Kray twins?

No, these guys had truly deformed huge honkin’ chins - perhaps enhanced by early special effects, as I can’t imagine these were real body features. I’m thinking they sort of resembled Baron von Munchausen, but with the chin being the same shape without the goatee. I think they did almost comical boxing, like the 3 Stooges…

Was one of them bright blue, the other bright red, with a lot of right angles?

(Sorry; couldn’t resist.)

The only chinned-up boxing twins I can think of are the Coopers - Our 'Enery and his brother George. Henry knocked down Cassius Clay (as they insisted in calling him) in 1963.

Hmmm. . . .

Was the movie a documentary (thus having real footage of these people) or was it a fictional story (thus having staged and probably made-up people as the twins)?

BTW, for anyone who didn’t follow the link: this question’s been asked and answered before.

And by the same OP too. That’s a little weird.

Kipper Kids is the answer then.

Nitpick: He didn’t become Muhammad Ali until 1964, so naturally they would have insisted on calling him Cassius Clay in 1963.

Just an indication of their narrow vision.

omigod…
I am so embarrassed…
Of course, that was almost seven years ago, and y’know, a lot of stuff under the thing and all…the truly humiliating thing is that when Mr. singular asked me, I had a nagging feeling I’d asked that before on the SDMB, but I didn’t think to do a vanity search. Sorry, everybody.
