Anno Domini XXXIII is a "wholly Maltese production" with a cast of over 400 according to The Times of Malta (see also here).
The film was written by Renzo Bonello who also directed the film (along with Melvin Schembri and Christopher Cassarby). Rennie Schembri plays the lead role in a cast also featuring Mario Camilleri, Maria Cassar Inguanez, Jolene Micallef and Jonathan McCay. Bonello and Schembri are quoted at length in the Times of Malta article.
The film's biggest expense however was the soundtrack. Ray Sciberras's score was performed by the 66 piece Bulgarian Philharmonic Orchestra and a 40-strong choir.
There's a trailer for the film on YouTube and a further article at di-ve.com.
