When Bruces character confronts A.J for sleeping with his daughter, he has his golf cub up to A.J's throat with the club head facing one way, cut's to Bruce to say somthing and when it cuts back to A.J the club head is facing the other way.
The golf club also changes when it is first shown in the movie. He is a left handed golfer and the direction of the club face is for a right handed hitter. Caught that the first time I watched it.
