Trailer for a remake of Gore Vidal's "Caligula" (2005) featuring Gerard Butler as "Prefect Cassius Chaerea". Directed by Francesco Vezzoli.

Thanks to Bluecabochon for the pictures. This is what she has to say about his appearance in this trailer:

His first appearance, in the beginning, within a montage of debauchery, shows him reclining while caressing the face of a woman lying next to him; near the end, he stares into the camera within his title card. Unfortunately, he does not speak and his scenes are very brief.

From dubhodhar - His character was Prefect Cassius Chaerea - he is the one who assassinated Caligula.
