Factual error: When Harrison Ford shoots at the T.V. in his office, he is shown holding a revolver. However, you can clearly hear ejected shell casings hitting the ground. There would be no ejected casings from a revolver.
Continuity: When Greg Kinnear is punching Harrison Ford he hits Ford´s shoulder, but Harrison Ford is taking his hand up to his face like he was being hit there.
Continuity: In the opening scene, when Sabrina's voice-over introduces us to the family set-up, she states that a Rolls-Royce had been purchased. The camera then settles on a Bentley (probably a 1994 mulsanne model) which then features prominently throughout the film.
Continuity: Just after Harrison Ford shoots the T.V. screen in his office, he walks up to it and touches it saying it's indestructible. However, when he walks away and the camera follows, you can see a bullet hole in the bottom left-hand corner of the screen.
