Good old BBFC and their transparency on ratings.
There is frequent use of strong language (‘f**k’); milder terms include ‘bitch’, ‘tits’, ‘asshole’, ‘ass’, ‘shit’, ‘pissing’ and ‘bullshit’.
There is occasional sight of a man swallowing unidentified pills and at one point crushing and snorting them. There is also brief marijuana misuse. The work as a whole does not condone drug misuse.
Infrequent moderate violence includes a sequence in which one man punches another’s face, knocking him down. There are infrequent moderate sex scenes, without visible nudity, as well as fleeting sight of breast nudity in a scene in which a man and a woman share a bath. There is also a brief glimpse of full frontal female nudity in a non-sexual context.
I’m now going for that ‘brief glimpse’.
