It’s 10 hours long. And it is about - paint drying! If you ever wanted to watch paint dry for 10 hours, here’s your movie! Also - it’s rated “U” in the UK, so it’s a family movie!
Basically, getting a rating was the whole point of this, as the censorship board has to watch the whole thing to rate it. So - I can’t deny I enjoy the thought of filmmakers trolling the BBFC like this. (The German self censorship board is no better in their inconsistencies and weird decisions, so I hope this film finds a German distributor, too!)
