When I was in College in the late 70s early 80s I took a film class and the teacher, I think his name was Breheny, had a lot of experience in Hollyweird, he told me on the first Star wars they actually had a cocaine budget. He was right because Carrie Fisher died with coke in her system and in the late 90s Harrison Ford kept going to this seedy biker bar on the lower east side of Manhattan and nobody could figure out why until it was found out the owner was dealing coke. They should have called that movie Coke wars
The coke could explain Harrison’s flying at times.
