This is an attempt to restore one of the more infamous deleted scenes from the 1976 "Caligula." Various different sources were used to piece the scene back to together, as well as putting some pre-existing moments back into sequence, so sorry for the uneven quality.
This scene was split in half by the inept editing crew that butchered the film (Macro's death scene was supposed to occur DURING Proculus' challenge) and the latter half was completely deleted when the film got released in US theatres. The scene was quite an important plot point, which would give more depth to the scene which follows it (Caligula sexually humiliating Livia and Proculus during their wedding.)
