British moviemaker Terry Gilliam is still fighting reports his pal Heath Ledger was experimenting with drugs at the time he died a year ago (22Jan09) - because the actor was "clean".
Ledger died from an overdose of prescription drugs he was taking to try and cure insomnia, but many suggested he was on much stronger narcotics - and the speculation continues as the anniversary of the tragedy approaches.
But Gilliam, who was working with Ledger on his final film The Imaginarium of Doctor Parnassus when the star died, is desperate to set the record straight.
He tells Entertainment Weekly magazine, "The insomnia was really getting to him. He'd arrive (on set) in the morning looking really shattered... (but) he'd just whip the thing up into another gear very quickly and off we'd go.
"They (media) tried to hard to pin (drug abuse) on him, but they couldn't because Heath was as clean as you could be.
"We know about the pills, but he had stopped smoking. Marijuana was no longer in his life... He wasn't drinking. Nothing. This was a body that had cleansed itself for over a year of anything."
