 The shot of Caligula being scared by a black bird while playing    with a rat was originally part of a much longer scene in which he    sets up many small chariots for a race to entertain his daughter,    and, thus, was also meant to be included somewhere in between the    I am God scene and the imperial bordello scene (along with several    other cut scenes (such as the sacrificial scene and the scene    where Caligula claims himself to be king of the gods) and    relocated scenes (such as Proculuss death)).
