Matthew Perry is said to have been so obsessed with Batman he called the assistant who injected him with his final doses of ketamine ‘Alfred’.

The ‘Friends’ actor nicknamed himself ‘Mattman’ in his final Instagram posts due to his worship of the caped crusader, which were uploaded before he was killed on 28 October, 2023, aged 54 from the “acute effects” of anaesthetic ketamine.

It’s now been reported by the Daily Mail Matthew’s live-in assistant Kenny Iwamasa, 59, was “known as ‘Alfred’ to Perry’s ‘Batman’” – in reference to the comic book vigilante’s 24/7 butler.

Iwamasa admitted in court documents he injected Matthew with three doses of ketamine in his final hours.

He made the confession in a set of plea agreement papers he signed after he and four others were arrested in connection with supplying the ‘Friends’ star with the drugs that killed the actor.

The papers show the injections were administered by non-medically trained Iwamasa from 8.30am on the day Matthew died in the hot tub of his $6 million Pacific Palisades mansion in Los Angeles.

They say after the first dose, Matthew’s assistant gave him another one four hours later – and yet another 40 minutes later.

It was before the third injection Matthew told him: “Shoot me up with a big one.”

The actor is said to have then told Iwamasa to start up the hot tub where his assistant later found him dead with his head in the water after his employee went to run a set of errands.

It’s also been reported by the Mail Matthew let go his nursing team – who had been on his payroll for years due to his addictions and health issues – before his death.

One source told the newspaper the actor “had very few people around him late last year” and was “very isolated” before his passing.

Matthew’s assistant Briana Brancato left the actor’s employ in 2023 after seven years, a year after his live-in sober companion Morgan Moses also stopped working for the star.
