The British Board of Film Classification [theregister.co.uk] (BBFC) has determined [bbfc.co.uk] that Charlie Lyne's 10-hour Paint Drying contains "no material likely to offend or harm", and has accordingly awarded it a "suitable for all" U certificate.
Nicely described by the BBFC as "a film showing paint drying on a wall", Paint Drying is the result of a Kickstarter campaign [kickstarter.com] aimed at highlighting the "prohibitively expensive" cost of presenting cinematic works for classification.
The BBFC charges a £101.50 submission fee and £7.09 per minute of film. However, it is obliged to sit through every single frame of material, so Lyne decided he'd make the censors work for their money.
