My Mum's Best Friend

Can only be shown at licensed adult cinemas or sold at licensed sex shops, and only to adults, those aged 18 or over. Films under this category are always hard-core pornography, defined as material intended for sexual stimulation and containing clear images of real sexual activity, strong fetish material, explicit animated images, or sight of certain acts such as triple simultaneous penetration and snowballing. There remains a range of material that is often cut from the R18 rating: strong images of injury in BDSM or spanking works, urolagnia, scenes suggesting incest even if staged, references to underage sex or childhood sexual development and aggressive behaviour such as hair-pulling or spitting on a performer are not permitted. More cuts are demanded in this category than any other category.
