During the second basketball game, the writing on the Ohio Leopards jerseys frequently changes from "Leopards" to "Ohio" on a shot by shot basis.
(At about 1:03:30) The main characters' college basketball team is the "Ohio Leopards." But when the coach jogs at the college stadium, a landscape shot shows the words "University of Oregon" on the stadium sign, revealing that the movie was shot there.
After Olive is seen typing and Hector comes to visit a crew member's reflection visible in the window.
Boom mics are visible in two scenes. First, when William Tepper / "Mike" is walking with a friend on a sidewalk and descends some stairs on a hillside. Second, when Tepper is in Karen Black / Olive's home, the low ceiling in the living room forces the boom mic into view.
In the scene at the market with Hector, Olive, and her female friend, a sign for "Mayfresh Vegtables" can be seen.
