pogues biopic with paul giamatti as shane macgowan

maybe i need my meds adjusted, but i have an irrational fear of really awful pogues movie with paul giamatti starring chewing the scenery as shane macgowan.  i understand that it is both less likely than a ron paul presidency as well as more horrible than a rick perry/david barton administration, but, still, it would be a remarkably destructive artifact, and i've been obsessing about it for a while.  bad mojo.
