The first time, when Meredith Johnson and Tom Sanders are meeting in her office, when Meredith's secretary comes to ask her boss if she could leave earlier right after Meredith grants her wish, the secretary leaves and locks the office door. But when Tom Sanders leaves after he is harassed by Meredith, he opens the door, as if it was not locked.
When Tom is using the "Corridor" to look through Digicom's files, the Operations "file drawers" are labelled "Operations Singapore", "Operations Malaysia", etc. Yet when he opens the Malaysia "drawer", the system audio announces it as "Malaysia Operations".
When Tom is driving to the Bainbridge - Seattle ferry at the beginning of the movie (with the Mt. Rainier in the background), he's actually driving away from the ferry down a dead end road on the island.
The mediation is completely unrealistic. In a mediation, no court reporter is present to make a transcript and the lawyers do not cross-examine the opposing parties; it is not a mini-trial. In reality, the parties explain their case to the mediator and the mediator tries to get the two sides to agree on terms.
