It has been listed for ages in KR's IMDb page as a project he is rumoured to be working on (title character of Johnny Stompanato) and is currently listed as being "in production" with a release date of sometime in 2010.

Now as recently as this week KR was supposedly in London so it seems unlikely he is making this movie and now they say he is scheduled to start 'Henry's Crime' later this year. I am not complaining (much) but if someone else is playing this role it seems like the least they could do is update the info and give credit where it is due
