Quentin Tarantino may have seen ALSO this one : the gang boss does not want his men can identify themselves, and he wants them to choose (or he chooses for them : memory is not sure about that) names of numbers or colors or anything else. Remind you something ? It is clearly one source of one of the good ideas of Tarantino in RESERVOIR DOGS. Tarantino has seen many movies : he makes homage to the famous first dialogue line of DEATH TRAP / EATEN ALIVE / STARLIGHT SLAUGTHER (USA 1976) directed by Tobe Hooper in KILL BILL, and to many others movies he has seen in his own movies. He liked what we liked in the 60's & the 70's. And because of his "history of movies" memories, we can even re-discover such movies as this quite funny DAY OF THE WOLVES ! As Latin proverb says : NIHIL NOVI SUB SOLE (Nothing new under the sun) !
