Taxi Driver (1976)
Turning more alienated and violent, in the most terrifying, but classic sequence in the film, he glares at himself in the mirror and recites conversations in which he threatens and insistently challenges imaginary enemies, rehearsing his quick-draw with his spring-loaded holster:
Yeah. Huh? Huh? Huh? (I'm) faster than you, you f--kin' son of a...I saw you comin', you f--k, s--t-heel. I'm standin' here. You make the move. You make the move. It's your move. (He draws his gun from his concealed forearm holster.) Don't try it, you f--ker. You talkin' to me? You talkin' to me? You talkin' to me? (He turns around to look behind him.) Well, who the hell else are you talkin' to? You talkin' to me? Well, I'm the only one here. Who the f--k do you think you're talkin' to? Oh yeah? Huh? OK. (He whips out his gun again.) Huh?
The conversation then becomes internal and disjointed - the film literally replays itself in a jerky rewind, reflecting the disassociated, obsessive nature of his mind, while he lies on his bed or again taunts make-believe adversaries in front of a mirror:
Listen you f--kers, you screwheads. Here's a man who would not take it anymore. Who would not let...Listen you f--kers, you screwheads. Here's a man who would not take it anymore. A man who stood up against the scum, the c--ts, the dogs, the filth, the s--t, here is someone who stood up. (A close-up of his diary entry, "Here is," is followed by three erratic dots.) HERE IS --- (He draws his gun.) You're dead.
