the pope must die (1991)

aka The Pope Must Diet.
"Serves you right, dealing arms in the Vatican!"
The fix is in for the election of a new Pope, unfortunately a miss heard name means that an unknown priest (Robbie Coltrane) is elected instead. So a plot is hatched by the Vatican, the mafia to rid themselves of this mistake.
Heavy handed satire that misses more than it connects with its punches.
