At 1hr 35mins, Zain ties Yonas's leg to the shoe stand to prevent him from following or wandering into busy traffic, He tied the right leg in the initial scene, and then after a cut back to that scene seconds later he is now tied by his left leg. which is not really his left leg, because the whole shot is reversed in order to have Yonas's look in the correct direction. you can notice this by the boots and the blue shoe in the background.
at 4:17, Zain is shown being handcuffed behind his back and taken to court. Arriving in the court house, at 5:22, still handcuffed, he manages to scratch his face which would of course be impossible to do.
A few seconds later, the judge asks that the handcuffs be removed, they were therefore definitely meant to be on a few seconds before.
Zain's hair grows over time, Yonas' remains the same.
On the rooftop scene at minute 18, the microphone windscreen is visible on the left corner. It's also seen behind the scene of the movie.
