A Sydney man said binging on horror movies including The Texas Chainsaw Massacre and Friday the 13th gave him the "taste of blood" before he stabbed an elderly cabbie 13 times, a court has heard.
Luke Woods, 36, is accused of the attempted murder of taxi driver Neal Kent, 72, who survived the attack with wounds to his shoulder, neck and head.
In a police interview played before the Downing Centre District Court on Monday, Woods said the violent movies made him feel like murdering someone.
"They kind of give me the taste of blood, I guess," Woods said in the interview after the incident.
"Making me feel like ... murdering someone.
"Like poor Mr Kent there."
Woods has admitted to a charge of wounding with intent to cause grievous bodily harm but has pleaded not guilty to attempted murder.
Woods said he used a large kitchen knife, which he nicknamed Stanley and kept under his pillow, to stab Mr Kent on December 30, 2013.
He said he had been watching horror movies "over and over" for weeks leading up to the attack.
"The Texas Chainsaw Massacre - I watched it quite repetitively," he said.
In the hours before the killing he watched The Texas Chainsaw Massacre, The Texas Chainsaw Massacre 2, Friday the 13th parts one, four and five, and Wrong Turn 4.
Woods told police he also drank 12 beers before climbing into the back of Mr Kent's taxi near Martin Place, in Sydney's central business district, and requested a ride to the inner city suburb of Surry Hills.
Woods then directed Mr Kent to a small car park at the end of a residential cul de sac, before slashing the cabbie in the shoulder, neck and head.
Mr Kent managed to escape, leaving Woods locked in the back seat of the car so that he had to climb through to the front seat before he could flee.
Woods said after the attack he threw the knife in a bin, went to a convenience store to buy some milk, and went home.
Woods, who was a ward of the Public Guardian at the time of the attack, said during his police interview that he wanted to be put in a "little special place" and be "looked after".
"I don't say I really have a life any more so I've decided to do this to put myself in some sort of facility," Woods said.
"I'm sorry for such a nasty attack.
"I didn't mean to go that far. I'm not managing life well at all.
"Karma's gonna get me."
The judge-alone trial continues before Judge David Arnott.
