While Brian de Palma's opening installment of the Mission: Impossible franchise isn't as action packed as the other installments, this sequence is one of the most memorable across all four movies. The set-piece was reportedly Cruise's idea, and the actor insisted on doing the stunt himself much to the dismay of the director.The explosion and subsequent jump through the window were shot on a soundstage at Paramount Studios, with Cruise neglecting to use a stunt double. No less than sixteen tons of water were used for the scene, and seeing the actor's face as he escapes only enhances the power of the scene, especially when you consider the very obvious drowning hazards.
