For those that may be interested. It is not a documentary with the Robertsons. It is a movie and they just make an appearance. Kevin Sorbo, Shane Harper, Dean Cain I believe the trailer showing the Robertsons is to get more people into the theaters and nothing wrong with that. The trailer has a lot of buffering. I would pause it for a bit and then start watching it so you don't get a choppy viewing.
Coming to theaters March 2014!
