should play a psycho
hed be great as a cowardly murderous psycho on the loose, absolutely off the charts mad man (I'm thinking abit like Scorpio in Dirty Harry), maybe abit autistic like Gump to make it even more disturbing
someone like Denzel or Crowe as the Dirty Harry type cop who has to take him down
Also he has no dialogue like at all. And he has to let his hair go longer and curly.. so hed sort of look like he did in the 80s but older
Robin Williams did the crazy psycho stuff great later in his career after starting out with comedy then went serious drama/Oscar stuff.. Hanks should do it
