Conrad Murray felt "entrapped" by Michael Jackson after agreeing to take him on as a patient, and insists the star frequently "begged" him for drugs.
The medic, who was convicted earlier this week (beg07Nov11) of accidentally killing Jackson with anaesthetic propofol, is adamant he did not suggest the Thriller icon should take the drug to help him sleep.
But he claims Jackson was an addict who "begged and pleaded" for strong medication.
Murray spoke to a film crew for new documentary Michael Jackson and the Doctor: A Fatal Friendship, which began filming in November 2009 - five months after Jackson's death - and is due to air in the U.S. on Friday (11Nov11).
He says, "I went there to take care of a healthy man, who said he was fine, to just keep surveillance. But once I got in there I was entrapped. He had very close acquaintances, but friends he did not have. He told me, 'I've found one friend, which is you'."
Speaking about Jackson's use of propofol - which the star referred to as "milk" - the doctor adds, "He begged and pleaded and said, 'Please Dr. Conrad, I need some milk so that I can get some sleep. If I don't get some sleep, everything will go down the drain.'
"He looked to me like (his image in) the Thriller (film). He looked that hysterical... I did not recommend it. I would never have recommended propofol to Mr. Jackson. He needed to get rid of it and resume a more normal state of sleep."
The documentary - which aired in the U.K. on Thursday (10Nov11) under the alternative title The Man Who Killed Michael Jackson - also contains a scene in which Jackson's lawyers, Ed Chernoff and Michael Flanagan, are heard discussing the star's notorious eccentric behaviour.
Chernoff says, "I think the media made him appear weirder than he is", prompting Flanagan to reply: "You gotta be kidding me - he can't be any weirder than he is."
