“Filmmaking is a much more collaborative thing than literature, so you know you're going to be working with a group of people at the start. You know it's going to be a compromise.”

Scottish novelist and playwright of the late 20th and early 21st centuries, Welsh is best known for his sharp, unflinching depictions of working-class life in Glasgow. His debut novel, *Trainspotting*, became a defining work of contemporary British literature, blending dark humor with raw social commentary. His later works, including *Filth* and *The Acid House*, continue to explore similar themes with equal intensity.
