Restricted - "Admittance restricted to persons 18 years of age and older. Content not suitable for minors. Contains frequent sexual activity, brutal/graphic violence, intense horror and/or other disturbing content."
This is the most heavily restricted category in use by Alberta Film Classification; no one under the age of 18 may be in the theatre under any circumstances.
Films such as Saw 3D (2010), I Spit On Your Grave (2010), Les 7 Jours Du Talion (7 Days) (2010) and Hobo With A Shotgun (2011) represent the range of graphically violent or sexually violent material in this category.
Extreme crude content that can include detailed depictions of bodily functions or crude activities, such as those found in the Jackass films, also receive the R classification.
