Power Rangers and Tarzan

My 6yo nephew is in to the Power Rangers. In the Wild Force season, the Red Ranger grew up in the jungle similar to Tarzan and TJ really likes this character, so I thought this would be a chance to introduce him to the Tarzan movies. I found a copy of the 1932 Johnny Weissmuller movie for him. Today my sister told me that he put it in the DVD player and when it came on, he called out saying that the DVD player was broken because there was no colour. My sister told him it was made when Nanna was a little girl - actually she was born the year after it was made. We didn't think to tell him about them olden days before colour. :)
