yeah Erik i saw that movie..there's a story from that period that says he was not eating at all, just a milk and cocaine diet. He was really thin and lost in that 1975. He said he does not remember at all that year. The funny thing is that he released Diamond Dogs, and Station to Station from 1974 to 1976, some of Bowie finest albums ever.
I always tought he seemed more an alien in '75 than in his Ziggy Stardust period.
