Thanks for the interesting info! Yes, The Lucy Show was filmed in color starting in 63. I read that they "splurged" on color film since they thought it would bring up the value in syndication. However, I still like to drain out the color on my set when I watch any 63-65 episodes of that show. It just suits it better...
Another question...any color episodes of Hazel I've seen don't seem to have a laugh track. It's almost as if after the switch to color it turned into a dramadey of sorts...is this true or did the episodes I've seen just not have any funny moments?
