Alice's bra is alternately on/off between shots during the love-making scene in the library.
In the bar, the martinis that Alice and her friend get start off as red and green, but by the end of the scene they are both clear.
During the breakfast scene between the Alice and Adam characters, the top on the jar of jam alternates between open and closed after Alice accesses the contents.
When Alice is being interviewed by the police, the papers on the table are sometimes in a file and sometimes not.
When Alice reaches for the doorknob of her office for the first time the newspaper in her bag is sticking out the back. But when she enters the office the paper is still in her bag but now poking out under her arm.
The bonds securing Heather Graham, as Alice, to the table, are obviously inadequate. She could free herself easily. While it could be argued that Alice was playing along, later on she urgently requests Adam to untie her. So, the ineffectiveness of the rope undermines the impact of the crucial scene completely. To put it bluntly, the way it was done, makes otherwise bright Alice look far less than smart.
When Alice is showing Deborah the Polaroids in the kitchen, there is movement reflected in the toaster and two white mugs in the cabinet that do not belong to the two characters.
