hmm interesting though I don't think I ever saw the Santa Clause.
Also I didn't know Tim Allen was an outspoken christian. I know he was on the tv sitcom Home Improvement though, which seemed to have a christian family theme though its been ages since I've seen it.
I do know Candace Cameron and her brother are christians (Full House and Growing Pains).
Mel Gibson too apparently (he was in Passion of the Christ)
Justine Beiber and Katy Perry and Britney Spears are also from christian families.
It's unusual for Disney to endorse Christiantiy though, or be overly 'religious'
Dreamworks did produce Prince of Egypt, which was based on the Moses story in the Bible. However Disney tends to stay away from Bible stories and stick with fairy tales
