Wasteman Premieres at BFI London Film Festival as Cast Detail Grueling 18-Day Shoot

The festival unveiling spotlights a debut feature shaped by intense production demands and raw performances.

Overview

  • The feature debut of Cal McMau follows inmate Taylor’s fraught dynamic with new cellmate Dee, probing violence, masculinity and survival.
  • The production was completed in 18 days with a claustrophobic approach, and David Jonsson says he lost 30lbs to play Taylor.
  • Jonsson credits his off‑camera bond with Tom Blyth for helping them decompress from the intensity, while Blyth says he often struggled to shed Dee’s tension after filming.
  • Co‑star Alex Hassell says the cast regularly reassured one another between takes and apologized for intimidating moments to keep the set safe.
  • UK theatrical release is scheduled for February 20, 2026.
