As Jourdan is about to have Murdock killed, Murdock says he knows all about "Operation Undertow". Jourdan dismisses it by saying "You know two meaningless words", but changes his mind and orders to lock Murdock - a reference to the way Bond persuaded Goldfinger to spare his life, by mentioning "Operation Grand Slam". The henchman Fröbe resembles Oddjob, and is named after the actor
Gert Fröbe who played the role of Goldfinger.
