The scene in which Caligula expresses his fears of being killed by Tiberius to Drusilla, and where he is frightened by a black bird is cut entirely.As well, many shots and lines of dialogue are juggled around. The scene in Tiberius's grotto is almost entirely alternate angles in the segments involving the drunk soldier, and in the pleasure building.The scene by Tiberius's pool includes many alternate angles, juggled shots, and rearranged dialogue to avoid showing male genitalia (and a new laugh is dubbed over at the end as Tiberius exits the pool).The start of the scene in which Caligula is being carried to the palace while nude slaves work on the road is trimmed to avoid showing male genitalia.The final few seconds of the scene are trimmed, calling for a much quicker dissolve than in the original cut. Several shots are juggled around, and Caligula's line "Macro!" is moved to a different shot. The scene following the credits is shortened it cuts from Drusilla saying "he's not!" to Macro entering the room.The final several seconds of the scene are also cut to avoid exposing Drusilla's genitalia. Later in the scene, they cut back to the herd of sheep to hide the cutting of Caligula sucking Drusilla's breast.
The eventual 1990 video release was the extensively edited U.S R-rated print and 55 minutes were cut from the film, resulting in most of the sex & violence scenes being removed in full or edited via long shot camera angles and a running time of around 98 minutes. This meant that additional edits were required and the film was then cut by a further 3 minutes by James Ferman himself with extensive edits to scenes of masturbation, lesbianism, anal fisting, castration, graphic stabbing scenes, explicit genital closeups and shots of babies being fed through phallic-shaped bottles. When the film was originally submitted in the UK it was cut by 8 minutes on legal grounds to qualify it for a possible private cinema club certificate, though the distributors decided instead to apply for an 'X' certificate for a wider cinema release.
