Who could play Slash in the movie adaptation of his autobiography?

Rumours are abounding that Slash’s fabulous-sounding autobiography - and if anyone wants to send me a copy, please feel free - could be made into a film. Sadly he reckons he’d need to change the names of the famous and guilty, but I don’t think that would matter. We’d be able to work out who the ginger egomaniac in the white cycling shorts is supposed to be.
So, with that in mind, who would make the ideal Slash? Or “character based on Saul Hudson”? I’ve wittled down the top 872 contenders to an elite of 5. They are:
Russell Brand
I’ve been hearing for about 12 years that he’s supposed to be playing a rock star in some Hollywood film or other. Add to that his own adventures in druggy shagging, and you have a serious, big-haired contender. May need to bulk up a touch.
Sir Anthony Hopkins
This guy can do the whole lot! I can see him with the fag, shades and frightwig right now. And I would dearly, dearly love to see him do the whole “tiny little men with guns in the lounge” hallucination episode.

Peter Jackson
Used to gore and disgustingness from his days directing movies like “Bad Taste”. Big scary hair. Adept at spending large amounts of money on pointless crap (see Lord Of The Rings series). Ticks all the right boxes.
Weird Al Yankovic
Used to playing “versions” of pop / rock stars. Has he done Guns N’ Roses yet? Would need to curb his “hilarious” side, mind you. Guitar solos on cliff tops are serious shit.
Alanis Morissette
She’s played God. She’s appeared in “Degrassi: The Next Generation”. She’s even had a bash at portraying an insightful rock singer. Next challenge please!
Can you do any better? Can you? Can you? Of course not.
