George, I've been meaning to ask this for a while now but does your son enjoy watching these older films? I've got a couple cousins under the age of 7 and I find it a lot easier getting them to watch B&W films than their parents. I think I've told this story before but two of my cousins (7 year old twins) were at my house as well as ten other family members (all older than me) and I was watching CITY LIGHTS. None of the adults got into the movie because it was silent and B&W yet the two girls really enjoyed it after I explained to them why these older films don't "look" like the ones made today.
If I ever have kids I'm certainly going to have them watching GUNGA DIN over some crap like WHITE CHICKS or any other "cool" film from today.
