Saw it. Blooming loved it, would recommend to anyone. Didn't notice anyone walking out, was in front section. Don't see why anyone would decide to walk out, it's a good movie.
Just been to see it a second time. Again a packed cinema and no-one walked out. Loved it and found it really moving. Maybe some people walk out because they didn't realise the dialogue is in Aramaic and Latin with English subtitles.
I didn't see it in the cinema (shame on me) but I noticed one scene where a member of a crowd shouts "He's not the Messiah!" I am dying to know if any audience anywhere responded in unison with the obvious "...He's a Very Naughty Boy!"
ha ha ha ha! i know! since i don't know much about the Bible apart from the basic plot but have seen the Life of Brian many, many times I found it really amusing how similar it was!
