Dunno.

haha.

Seriously, though, I would think it would come up once or twice in the gospels, in letters and other references, etc. If nothing else, to follow a point Gryx made below, try to tell me that there wouldn't be sub-cults and other groups of folks that were followers of Jesus' kids, believing them to be of some holy nature, etc.

In the end it doesn't matter, and I'm interested in seeing the movie just because.
