First 5 minutes of Inception
Silver Warner Bros. and Legendary Pictures logos go by, then we hear that "BRRRRRRM BRRRRRRM" sound over and over, getting louder each time until it's unbearable, then it suddenly is silent--and it cuts to a slow motion shot of the waves of the ocean, then it shows Cobb lying face down on a beach. He looks up and sees his kids playing in the sand. A security guard with a rifle walks up to him and uses it to lift up the back of his jacket, revealing Cobb's handgun. He yells something in Japanese to someone off-screen.

Then we cut to the inside of an old Japanese man's mansion, with two guards dragging Cobb in and sitting him down in a chair. The Japanese man (who we later learn is Siato) is extremely old. The man takes out Cobb's "totem," the spinning top, and places it on the table. He asks, "Are you here to kill me?" Cobb looks at the totem and asks, "do you know what this is?". The old man then says something like "I once knew a man who owned one, a man delusional of many notions." (at least that's what I heard) Cobb looks up. Cobb is very confused and struggles to remember what he's there for... He tells him he came to remind him of something he used to know... that this world is not real.

Then, suddenly, Saito is younger and is sitting in the same room. Cobb and Arthur are sitting with him. Cobb explains how he is the most skilled extractor, thus he can help protect Saito from other extractors. He says he needs to know what's in Saito's safe (yes, he has a safe too) in order for him to understand how to navigate his mind. He is trying to lure Saito into helping him steal his own ideas. Saito gets up and goes out into the other room where there is a party going on. Cobb and Arthur stand up, then notice that everything starts shaking.
