30 minute mark
I started watching this when the movie was already thirty minutes into, then I watched it again from the beginning.
I will say watching this at the point he is boarding the plane makes the movie more interesting, you really want to watch it all the way through to find out why he is being arrested and what happened, you start to get an idea and then you know more when you see the African American woman point him out at the police lineup, from that point on, you wonder whether he did it or not.
watching the first thirty minutes gives away the whole movie, everything after thirty minutes is expected and known to the viewer.
I think this movie should have started out with him boarding the plane, all the viewers questions from that point on would have been gradually answered during the movie, which is what makes a good movie.
