Continuity mistake: After Bud asks Carl for money at the bar, a friend comes up and Carl shakes his hand. At this time Carl doesn't have glasses on. Bud then asks Carl "How's work been treatin' you." When he asks this the camera angle is over Carl's shoulder and he has glasses on. Then in a front shot, the glasses are in his hand, but there was not enough time for him to take them off.
Continuity mistake: When Gordon and Bud are getting dressed after playing racquetball, Bud is seated with what looks like a can of soda on the bench to his right. He drinks from the can. Less than a minute later when Gordon says, "I've been in this business since '69," Bud drinks from a glass.
Continuity mistake: When Buddy first meets Gordon Gekko, Buddy is depressed as he walks towards the door of Gekko's office. The door is opened, and as Buddy turns to look at Gekko his tie is perfectly placed. In the next camera angle of Buddy walking out of the office his tie is pulled down.
Continuity mistake: When Bud and his father are in the Owl Tavern discussing the FAA ruling for Bluestar, Carl says, "We can go for those new routes to Pittsburgh and Boston now. We're gonna compete with the big guys." With his right hand, Carl drinks some of his beer while his cigarette is left in the ashtray. When the camera angle changes to Bud, his right hand is holding the cigarette.
Continuity mistake: At Gekko's party Bud is introduced first to Sam Ruspoli, Carmen Winters, then Stone Livingston. After Bud shakes hands with Ruspoli he extends his hand to Winters who remains seated. When the camera angle changes Bud shakes with Livingston but the handshake with Winters has been cut from the footage. The changing camera angle reveals another error. The paperwork that Bud gives Gekko inside his front door is now folded in half but the action to fold the papers has also been cut.
