Simon Peter was never in Rome...
Does it not bother some that this movie depicts some events that NEVER occurred? Simon Peter was NEVER in Rome. He was imprisoned in Babylon, or ancient Iraq, by the Romans. The Roman Catholic Church only uses this fallacy to substantiate a false doctrine that Emperor Constantine exploited to start the Universal (aka Catholica) religion in the 4th century CE. The Apostle Peter was NOT the ROCK Jesus spoke of. The Greek word Petros (or Peter) meant pebble or stone. Jesus was referring to himself as the ROCK he would build his congregation on NOT Peter. Hence the Vatican is based on a clever lie.
Also Bruce Marchiano makes a terrible Jesus. Probably looked nothing like him nor acted like him. Jesus was a tanned-skin middle-eastern Jew. The actor Robert Miano's skin color looks more like what Jesus' complexion would have been. He would have probably been average height of 5' 11" or so. Bruce is not that tall. Bruce smiles too much. There was much Jesus had nothing to smile about. Also what's with the Trinitarian confusion about who is Almighty God? Is it Jesus or the Hebrew God Jesus worshipped and called Father? This movie makes it unclear who Simon Peter worshipped when it is clear that he too worshipped the Hebrew God not Jesus himself who is only the Hebrew God's son.
There is no credible evidence that Simon Peter was executed at all. Dionysius and Origen Adamantius said he was but their political motives are suspect. Since God miraculously freed Simon Peter from his first incarceration by Herod Agrippa it stands to reason that he may have died of natural causes this time around. Herod had died mysteriously at least 20 years earlier.
The jailers Processus and Martinianus are also Roman Catholic Church fictional characters in my opinion. A story woven to help establish the RCC in Rome by Constantine (true founder of RCC), who himself was never a real-Christian but a pagan up until his death bed baptism as a so-called Christian.
