(at around 26 mins) In Suki's room we see a set of 3 Hi-Fi components stacked on each other: 2 silver (cassette deck and amplifier) and 1 black (cd-player). In the first shot we see the black one (cd) stacked in the middle with the two silver ones on top and at the bottom. After a while (next close shot) we see the same components but they are stacked differently: The black (cd-player) lays at the bottom with the two other silver components on top of it.
(at around 1h 25 mins) Boom mic is reflected in a mirror while Keyes is approaching the dinner table with the shotgun.
