Audio problem: When Chris drives up in the truck while Selena is mowing the lawn, Selena asks what he got. While you hear "junk food" his mouth says something else.
Continuity mistake: When Howard supposedly has radio sex with that blonde woman, it flashes to other locations where people are listening, including one with police officers standing by early to middle 1990s Ford Crown Victorias. Howard did the stunt in the mid 1980s.
Continuity mistake: When Billy Connolly and his on screen brother have just been for a swim, they are drying themselves off on shore. Just to the left of his brother you can clearly see someone windsurfing in the background - not bad for the late 19th century.
Visible crew/equipment: When Brad Pitt is taken prisoner by the English, he tries to escape and is thrown in prison. As the camera turns back to the door, the shadow of a microphone is visible left to the door.
Audio problem: When the child is being tested for what objects he picks up, he handles one of the bells by holding the clapper, yet still the bell chimes.
Revealing mistake: Towards the end of the film when the Yankees are trying to close out Game 6 of the World Series you can tell the "real" footage they use is not from the World Series. They are playing the Atlanta Braves in the World Series but you can see the Baltimore Orioles logo on the field in a number of shots.
Continuity mistake: The rich promoter has red on his vest, before Don King throws his tomato juice.
Other mistake: When Oscar Wilde visits his wife's grave near Genoa, the headstone states "Wife of Oscar Wilde". It originally stated only "Constance Mary, daughter of Horace Lloyd, Q.C." and "Wife of Oscar Wilde" was not added until later.
