When Joey is talking to Ben about acting, the order and color of the blocks Ben is playing with changes in the middle of the scene.
When Raymond thumps the table and says: "Come on!", his soup spoon jumps between shots from being held in his right hand to resting in his soup bowl.
When Rachel is talking to Kim and Nancy about quitting smoking, there is a close up of Nancy and Rachel and Nancy has her right arm tucked under her left arm pit and then in the wide shot, Nancy's arms are both in front of her.
Joey's snowcone changes during the scene with Ross at the party. It goes from rounded to more flat to rounded, and from plain ice to being able to see the flavoring to ice again.
When Candler says: "Wish I had smoked for my career" he is looking at front with a sad face, but when the shot cuts back to Rachel, Monica and Chandler, this time Chandler is looking at Rachel without no time to turn his face to her.
After the callback and the casting director announces that the pairings will be Raymond and Joey and Kyle and Ben, she says that one of the two will be the final call. Joey screws up his own audition, but Ross says Ben didn't get the part either. If it was possible for neither to get the part, there would have been no need for Joey and Ross to fight in the first place.
