Deliberate mistake: The way the helicopter fell into the stadium at the end is impossible. Since the dead guy still held the control stick back, the rotor blades would still be pointed backwards making the helicopter fall even more back. Since there wasn't any controlled steering, it would spin around wildly. Not even a stunt pilot could maneuver a helicopter like that not to mention a dead body.
Sudden Death (1995)
1 deliberate mistake
Directed by: Peter Hyams
Starring: Jean-Claude Van Damme, Powers Boothe, Raymond J. Barry, Whittni Wright
Continuity mistake: Jean Claude Van Damme has just killed a terrorist in the hallway of the sports complex. He drags his body into an elevator to hide the body. The "terrorist" is far too tall and lifts his head out of the way to fit into the elevator. Can be seen just as the doors are closing. Very easy to spot.
Vice President: You have no idea of the complexity.
Joshua Foss: I had an idea, I had this idea, and we are gonna make it work or we're gonna die trying. You will call the President, and on flash precedence priority, he will call the Secretary of State and the Secretary of the Treasury. Then banks will be notified, and the money will begin to move. Or it won't. And if it doesn't, when the game ends, everyone in this box and in this arena will die by explosion, fire and panic.
Trivia: At the time of the movie's release, nearly all the players from the Pitsburgh Penguins depicted in the film (Luc Robitaille, Ulf Samelsson, Greg Hawgood, etc), were no longer with the Penguins. They were all either traded, went free agent or released.
