 Her performance in The Dreamers led Ridley Scott to cast Green in Kingdom of Heaven ( 2005 ) , a film about the Crusades where she played Sibylla of Jerusalem . Green performed six screen tests and was hired only a week before principal photography began . Green found the atmosphere of coming onto a film so late tense and exciting , and she liked the film 's ambiguity in approaching its subject matter . To her disappointment , much of her screen time was cut . Stephanie Zacharek of Salon.com praised her performance : " She doesn 't quite know what to do with her character 's stilted dialogue , but she carries herself so regally that you barely notice . " Nev Pierce of the BBC , however , called her character " limp " . Green was satisfied when her character 's complex subplot was restored in the director 's cut . Total Film said the new scenes completed her performance : " In the theatrical cut , Princess Sibylla sleeps with Balian and then , more or less , loses her mind . Now we understand why . Not only does Sibylla have a young son , but when she realizes he 's afflicted with leprosy just like her brother Baldwin , she decides to take his life shortly after he 's been crowned king . "
