"We come together tonight in a spirit of terrible mourning and incredible loss,' the Rev. Jim Martin, a Jesuit priest and LAByrinth member, told the crowd of about 200 people. 'But we also come together to celebrate a remarkable life.'

"Courage was his forte, always," said playwright and actor Eric Bogosian, a longtime LAByrinth collaborator. "'Phil set his bar on the highest rung, on a rung above the highest rung.

"He pushed himself relentlessly until finally his efforts virtually redefined the very endeavour we call acting. That's what he wanted. He wanted to rock the world."'

A larger memorial service is being planned for later this month.

Oscar winner Philip Seymour Hoffman allegedly admitted checking himself into rehab after snorting heroin.

Hoffman was nominated for Academy Awards on four occasions and won the Oscar for best actor in 2006 for his portrayal of writer Truman Capote in Capote. He was nominated three times for a Tony Award.

The celebrated actor died of a suspected heroin overdose on Sunday 2 February, at the age of 46 at his home in the West Village.

He had waged a public battle with drug addiction and suffered a relapse after being sober for twenty years. He entered rehab in May last year, but his addiction spiralled out of control.

He was found with around 70 bags of heroin inside his apartment O'Donnell phoned his friend Katz to check on him after he failed to collect their children at 9am.

Following an investigation into Hoffman's death, three people have been arraigned on drug charges, including one who is facing a felony charge of heroin possession with intent to sell.

Lawyers for the three people charged vigorously denied their clients had any role in Hoffman's death.

Autopsy results were inconclusive, authorities said this week.

The Church of St. Ignatius Loyola has previously been the venue for the funerals of Jacqueline Kennedy Onassis, Lena Horne and Aaliyah.
