Filth - Jon S. Baird (2013) How the Hell Have I Never Even Heard of a Movie Based on an Irvine Welsh Book?

How the hell did I miss this? I mean, I spent much of 2013 in the hospital and I did not have time to notice films coming out at the time.

But how did nobody tell me about a new movie based on a book by Irvine Welsh?

The trailer reminds me of Abel Ferrara's 1992 masterpiece, "Bad Lieutenant."

I must see this film next. Forget the current movies, you'll have to pardon me for enough time to watch an older movie.
