More than a family film--this fits well into various subjects chosen by Losey to make a film. Here the tale is an allegory of people being different from the majority and the importance of being accepted as such. Hair color, skin color, political affiliations, a virus carrier during the Covid pandemic,... society has to realize all are humans and equal. Howard Hughes, the RKO studio boss, tried his best to interfere with Losey's project and tweak the screenplay by threatening the child actor Dean Stockwell to change his spoken lines. History has it that young Stock-well was convinced of the lines he was speaking and refused to heed the angry Hughes!
