Roger Avary helped write the first Silent Hill movie and was set to work on the sequel as well. However, he got in a car accident while drunk and spent some time in a work furlough program and prison before being released recently; the whole incident has had a negative impact on the production of the film.

“[Silent Hill 2 is] little stalled now because of [writer/director] Roger Avary s [legal problems], so a little unsure yet,” wrote Silent Hill 2 producer Don Carmody. “The original plan was Roger writing and polishing the screenplay, and when he had finished his thing, we’d begin full-blown preproduction. I m not sure what s going on with that. We know we want to make Silent Hill 2 and have a basic outline for it. We ll have to see.”
