The hole Bruce makes in the paper wall with his samurai sword is missing in all subsequent shots.

In the movie, "Bruce" sees the Boss of Bosses giving Freddy the "Kiss Of Death" and mentions that he knows about the kiss from watching the Godfather movies. "Bruce" also tells the Boss of Bosses that he doesn't kiss as well as Marlon Brando. Marlon Brando never actually gave the kiss of death in the original film "The Godfather"; it was actually first bestowed on John Cazale by Al Pacino in "The Godfather Part II."
