A man accused of murder snapped at his alleged victim after he insulted a character in a vampire film, a court has heard.
Allan Menzies became obsessed with the vampire film
Allan Menzies, 22, denies murdering Thomas McKendrick at Mr Menzies' home in Fauldhouse, West Lothian, on 11 December last year.
The trial at the High Court in Edinburgh heard that Mr Menzies attacked his friend over the film.
Mr Menzies had watched the Queen of the Damned about 100 times.
Mr Menzies is charged with repeatedly striking Mr McKendrick, 21, on the head with a baseball bat or hammer and stabbing him in the head, face and body.
He offered a guilty plea to a charge of culpable homicide on the grounds of diminished responsibility, but this was rejected by the Crown.
The court heard that Mr Menzies said during a police interview that he lashed out at Mr McKendrick after he made comments about Akasha, a character in the film.
But Mr Menzies later denied he attacked his friend and claimed he did not know what had happened to him.
During the police interview with DC Gary Boyd Mr Menzies described becoming addicted to the film, playing songs from it "over and
over again" saying "it sent me mad quite literally".
He said he also became addicted to the idea of being a vampire, the court heard.
'I'd sell my soul'
Mr Menzies told police: "I thought if there really is a God I'd sacrifice this life for the next.
"This life is short, I'm 21, nae future so I figured I'd sell my soul for this life to be reborn in the next which now seems mad even to me."
The court heard that police told Menzies that his friend's blood was found at his West Lothian home and had soaked into the floorboard.
Mr Menzies said: "Well you should watch who you insult in life."
The trial continues.
