Star Trek (2009) movie won't play back properly in Apple TV Roku app

Star Trek (2009) plays back, but only with a very narrow horizontal strip viewable in the middle of the screen. I know some films have letterboxing, but something is wrong as though the letterboxing is way too big at the top and bottom, leaving just a narrow strip viewable. If I try to fast forward then is just turns purple. It's like this specific movie is broken in the app. Other movies in my iTunes library play perfectly fine. This is on a brand new TCL Roku Smart TV 55S525. Roku software is fully up to date. See attached photos.
