He still has that cocaine "tic" that most cocaine addicts have but it's ok, he will always be one of my favorites, from the U.S marshalls movie all the way to Endgame, great actor
You'd have to know an addict to see it, i guess, but @awake_ash is right... he still has it. That "eccentric" part? Yeah, no... that's a mind unfocused. Still though, he is Iron Man. <3
the thing is he was a great actor before this time and then fell off and had an amazing comeback, he was nominated for an oscar before getting arrested for drugs
