Movies always are open to being remade because times change so much and the tempo of movies changes. I think of it like a James Bond. They can have different actors play the same role... I've had people come up to me and say 'We want to remake 'The Jerk' with so and so.' And I say 'Fine.' It just doesn't bother me. It's an honor actually.
With any work worth its salt you have to trust the author enough to take its measure. And if you apply too many preconceptions you are not taking its measure.
