When Roman is on his bed talking to Olivia, the blanket covering him changes throughout the scene, sometimes hiding and sometimes showing his nipples.
At approx the 34:00 mark, you can see the shadow of a cameraman and his equipment across the front of the playground house going left to right.
At 42:51- in the kitchen when Olivia & Roman are talking you can see the pole for the boom mic reflected in the cappuccino maker.
