It's parody, people.
Or satire, I should say.
Anymore, you never know....
"... Next time try a movie about the Apocrypha, Mel."
Clear reference to Gibson's statements concerning possibly doing a film on the Maccabees. Catholics accept I and II Maccabees as Scripture (Deuterocanonical) while most Protestants do not (Apocryphal).
Either way you see it, great material for an action packed Gibson film!
