if superman made a cameo

He was already deceased when this aired.

Good choice (look like cavill)

also Steve Reeves (also abit Cavill-esque ,, pretty sure they model some of Cavills look in MoS on Reeves Hercules )

That's a good choice. Although he's a decade younger than the late Adam West, I do see that he was already fairly well established as an actor by the mid-late 60s, and he does indeed look the part.

I like that.

Chuck Connors played Superman *on* Superman..

worse suggestions were made above.
