デヴィッド・ニーヴン
At one point in the story, Bertie defends his moustache by stating that a moustache looks good on the actor David Niven, with Jeeves replying that a moustache suits David Niven but not Bertie. David Niven had portrayed Bertie Wooster (with a moustache) in the earlier 1936 film "Thank You, Jeeves!".
