First rule of arm wrestling club
Is David Lynch poking fun at David Fincher and Quentin Tarrantino?
The arm wrestling scene was like a spoof of fight club, his casting of Jennifer Jason Leigh and Tim Roth, The scene where Dougie takes a box out into the desert and it turns out to be Cherry Pie.
And outdoing them at their own game in many ways. Lynch is obviously an incredibly responsive cinephile.
Tim Roth must've had fun playing the character, being 180 deg. from himself.
