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.
Did anybody get a sound capture of the two things Walt said? Sounds like more reverse-speak. (EDIT: According to TVGuide.com, Walt said "The Others are coming; they're close." There was another secret message too though, right?)
