anyone remember this old film logo

Good stuff

Tom & Jerry

space ghost?

Yes - animated on screen, with the lion roaring. Back in the days when companies had very artistic trade-marks, not the bland and usually meaningless "Branding Consultants" squiggles we see so often now.

I must admit I'd not previously spotted the Classical Greek drama reference in it.

I do.

There’s an urban legend around this lion logo, isn’t there? It was meant to be silent, but two burglars ran past during filming, causing the lion to roar and maul one of them?

[mertchantofoldeurope] yes i have seen on old m.g.m films

Yes I do! It was popular when I was a kid.
