When Mary approaches Phil to say goodbye before leaving with Torg; there are two workers standing beside Phil and Mary watching them attentively. But on the next immediate shot when Mary and Phil are talking; there is only one worker sitting down cleaning equipment. Another worker approaches the first but they both remain oblivious to Mary and Phil. But on the next shot after that; the two workers are back once again standing next to Mary and Phil and paying attention to them.
While Tom and the other members of the troupe are packing; at one point the hidden overhead lighting used on the set begin to blink.
