The earliest editions were done on some kind of wire -- not film, which kind of gives those episodes an overexposed look. A number of years ago, I know there were some "experts" trying to figure out how to restore the wire versions...don't know if they ever found a way, but I think you may be able to find some tape or dvd copies.
What I remember about the color versions were that they were part of Gleason's variety show. I remember Gleason would introduce the cast at the very end of his show...and Carney always got the biggest applause.
Carney was probably the best, or certainly one of the best, second bananas ever. His comedic timing and mannerisms were just impeccable. One of my favorite running bits was his Ed Norton character about to, say, sign something or play the piano...he would go through this elaborate preparation -- cracking his knuckles and the like -- till the very impatient Ralph Cramden would just explode. Funny every time.
Or my other favorite -- the time Ralph and Ed were going to learn how to play golf. The instruction book says, "address the ball." So Ed gets on his hands and knees up to the ball and says, "Hello ball!"
Doesn't sound so funny in print, but to see it on the screen, it's a hoot.
And Alice -- some femnists complained that she was abused by her husband. But if you watch these shows, you know this woman always in some way got the best of him. And despite all of Ralph's bluster, he loved his wife deeply.
One of the all time classics. No remake will ever come close.
"Hey, Ralphie boy, you ready to join us denizens of the deep?"
"I am ready, Oh Captain Video!"
Ralph: "When you were in the hospital because you got hit in the head with a baseball bat at the picnic game, who brought you candy? Who read you comic books? Who came to see you every night?"
Norton: "Who hit me in the head with the baseball bat?"
Remember the time when Norton was reading a book, and he turned the page and said, "Paganini". Ralph did a double take, and said "What"? Norton: "Paganini". Ralph grabbed the book, and screamed, "Page Nine!!!!!"
