O'Brien met George Harrison when the former Beatle was looking to extricate himself from Allen Klein's management.
[4] O'Brien ran HandMade Films, as well as acting as executive producer for Life of Brian, and later productions such as The Long Good Friday, Time Bandits, The Missionary, Mona Lisa, Withnail and I and Nuns on the Run.
The company ceased operations in 1991[5] and was sold three years later to Paragon Entertainment, a Canadian corporation.
[3] The court found that O'Brien had mismanaged HandMade and ruled that he should pay Harrison $11 million.
According to Eric Idle of Monty Python, Harrison wrote the unreleased song "Lyin' O'Brien" about his former manager.
