 Despite initial fears of an R18 certificate (preventing the film  from being shown publicly and therefore ruling out its initial  premiere at Londons Tate Modern) the film was passed completely  uncut and granted an 18 certificate by the BBFC. The BBFC president  Sir Quentin Thomas said that the film was "so explicit that it would  normally attract an R18 rating" but he judged that "it was a work of  art not intended to arouse". All UK DVD releases carry a warning  which states that the film contains strong, real sex.
