Near the end in Charlie's trailer, an Oscar statuette is visible in the background standing on a white shelf. In the next shot, the statuette is on top of a black box that is on the white shelf. The following shot has the Oscar back on the white shelf. A few moments later, the statuette is knocked over and is seen toppling from on top of the black box again.
When Charlie and Irene are sitting in a restaurant waiting for Waldo, Charlie opens his cigarette case and takes out a cigarette. A couple shots later, the cigarette is lit, and Charlie is smoking it although he is not seen lighting it.
