It's hard to know where to start with the mysterious Mancunian Mark Gill, who, as you ask, looks like Lee Harvey Oswald (according to Oliver Stone that is).
At 18 he was a guitarist in Monaco (the band).
He is obsessed with Japanese culture.
He has a photo book collection insured for an offensive amount of money.
And has just published his own. 'The Airborne Toxic Event'. You should buy it.
He has an eighteen month old Maine Coone 'Muezza', which stalks him religiously.
He is both Oscar and BAFTA nominated for his work.
Well... that's a start at least.
