I've read up about the real life event when I heard Scott was going to direct this. Does the script stay true to the real story?
With regards to Scott's next film, my money is on The Cartel. He already did some location scouting for it back in the beginning of the year in Mexico and Spain. I suspect it's just about ready to go. Although, like you I would prefer he did Wraiths or otherwise BoB first. The Covenant sequel is probably unlikely at this stage since Fox is busy re-assessing the whole prequel trilogy.
