Query: What a great comedian!

Rich's impressions are so great. He's so versatile and really captures the person he's impersonating so very well. The story is well done and keeps to the original Christmas Carol story with a few minor changes. There's really a variety of characters. My favorites were James Mason, Jimmy Stewart, Richard Nixon and John Wayne. I loved this when it was shown on HBO in the late 70s. I watched it as many times as I could when it aired. I'm so glad it was available on DVD. The quality was very good. I watched the "behind the scenes" which ran the show again, but had the director and Rich Little explaining how the show was put together.
