Continuity mistake: When Whoopi Goldberg goes to the funeral, she sees Annie Potts. As the two of them are walking away afterwards, a man in a wheelchair is pushed by them, and he says hello to them by name. He then goes on ahead of them. Whoopi asks Potts who he is and he is one of the men listed on the frying pan, so she runs after him. This bit takes just a few seconds. His car is already pulling away, however and she misses him. But...the car was about 50 feet away, and he was in a wheelchair. How could his assistant get him to the car, then get him into the car, and stow his wheelchair in just a few seconds?
Other mistake: In the scene where Terry is at the computer, and Jim Belushi's character surprises her while pretending to be a Sperry repairman, they keep turning the monitor on and off. But the last time you hear a beep, which is supposed to be Terry turning off the monitor, her hand is nowhere near where the button would be. They obviously added the sound effect later.
Factual error: After escaping from the back of a NYPD cruiser that apprehended her at the British Consulate, Terry runs into the NYC 57th Street N/R line subway station. In the very next shot, she is running past Cole's French Dip Restaurant on 6th Street.in Los Angeles. The restaurant sign even mentions its location.
