So, here's an interesting tidbit that I came across yesterday. Apparently, the actor who played John in the temple movie was one of the people who signed a petition to the First Presidency during the Prop 8 days asking that church mind their own business. His reprimand for performing such a heinous act was to be removed from the temple film. Edited right out. Read the details here at the Wheat and Tares blog.
It's a good thing that Hollywood has made such great technical progress over the years, otherwise the editing would be really noticeable.
Too bad they didn't do it South Park animation-style. :P
