In the beginning of the movie Monk walks out a building whilst being on the phone and holding a coffee cup with a vertical print of the brand Dunkin Donut. Seconds later when he gets into a car, the logo on the cup is horizontally printed.
At 01:39:33, Monk has his arms resting on the table and in the next shot he immediately has them at his sides.
At the wedding, Maynard is wearing an Army officer's uniform with captain's bars, showing he's a junior officer. But his garrison cap (hat) is an enlisted version.
The young director Wiley is described by Monk's agent as a maker of Oscar-bait movies and yet, in his brief meeting with Monk, Wiley proceeds to outline the plot of Plantation Annihilation; clearly not a serious-minded film.
