I always loved Red Buttons. He was great in movies like "The Longest Day" (" Loud and Clear, sir!" and the Poseidon Adventure, but he was also great on all the TV shows I remember from when I was a kid. He'd be on Johnny Carson, Dean Martin, even Laugh-in. A funny, Funny guy, especially for an old guy. The Times did a nice Obit for him, and it's worth reading.
No John Williams theme has me concerned. It just seems like trying to go this "New" route is just shoving Superman I and II into the same film. I would like to see this movie due well if anything to get the Justice League movie going.
