Wise Man #1:
Brian's mother: Oh!
Brian's mother: Who are you?
Wise Man #2: We are three wise men.
Brian's mother: What?
Wise Man #1: We are three wise men.
Brian's mother: Well, what are you doing creeping around a cow shed at two o'clock in the morning? That doesn't sound very wise to me.
A Roman centurion in full dress would be recognizable by 3 things: greaves covering his shins and knees, a vine in his hand and especially a helmet with the crest positioned from left to right. John Cleese's centurion is wearing none of these badges of rank. His helmet is in fact more like that of a Roman general.
At the end of Idle's song "Bright Side Of Life" we can hear him saying "It's the end of the film. Incidently this record's available in the foyer. Some of us have got to live as well you know. Who do you think pays for all this rubbish? They'll never make their money back, you know. I told him, I said to him, Bernie, I said, they'll never make their money back... That should give you enough."
The film was originally over two hours long, but was edited down after audience previews. Amongst the scenes that were cut were an opening sequence in which the three shepherds attend the birth of Brian, and more scenes featuring King Otto, some of which were restored for the DVD release.
