Screa4m is a 2011 US horror by Wes Craven.
Notably it is the first in the Scream series to qualify for a BBFC 15 cinema rating rather than the usual 18 rating. Hopefully a result of the BBFC trend to more realistic ratings rather than any watering down of content.
In the US, the cinema release is R Rated which generally covers both UK 15 and 18 horror film ratings.
The BBFC offered the consumer advice: Contains strong violence, gore and language and further explained:
Screa4m is the fourth instalment in the popular series of horror films, in which the masked killer returns to the town of Woodsboro. The film was classified 15 for strong violence, gore and language.
Like the previous instalments, SCRE4M is steeped in a deliberate awareness of its own history and that of the horror genre in general, with characters regularly commenting on modern horror films. This invests the action with a knowingly comic and ironic edge. The BBFC’s Guidelines at 15 state Strong threat and menace are permitted unless sadistic or sexualised and Violence may be strong but should not dwell on the infliction of pain or injury. The strongest gory images are unlikely to be acceptable. Strong sadistic or sexualised violence is also unlikely to be acceptable. The attacks on victims are preceded by tense and terrifying set-ups, which carry a strong sense of menace and which contain the kind of jump moments that are a staple of the horror genre. However, this sense of threat and menace includes no significantly sexualised elements and nor does the violence itself, which is mainly executed by the masked character of Ghostface. Stabbings and slashings have bloody consequences, with injuries seen on faces, bodies, and on the walls and floors of various domestic settings. However, the attacks have a frenzied nature and are rapidly-paced with no undue dwelling on their gory results, nor any strong sense of sadism in the violence.
The film also contains multiple uses of strong language. At 15 the Guidelines state There may be frequent use of strong language (for example, ‘fuck’).
