Trying to get a similar film made
As a long time Richard Stark fan, I have to say that John Boorman's post-modern masterpiece is the only film that really brought a level of commentary to the source material.
For a long time, i've been dreaming of doing my own version. In the process, I developed something of my own named Striker. Though the protagonist is Parker inspired, the film series (I want it to be a whole franchise, anyway) is quite different but I can't imagine a Parker fan not liking it.
I'm trying to fund a short film on Kickstarter to do bigger things with the material in the future:

Though we are at 40%, we only have 4 backers. So I'm hoping things get better.
