julien breughel be call jean brueghel in other report of the film . i think that he must be jan brueghel the younger . that real life painter be the son of jan brueghel the elder . he would have turn 15 in the year the film be set . the duke mention jan father paint to jan. jan live in antwerp at this time and i think . boom seem to be a flemish town close to antwerp . the dutch ( at least in holland ) be neutral and not invade during the first world war . so erniemunger comment about dutch collaboration during that war seem wrong . belgium be neutral until it be invade . perhaps the commenter mean fleming when he say dutch ( i know nothing about any such collaboration represent i be not make an accusation ) .
