Miscellaneous: When John Kent arrives in Paris and goes to the building where Roberta lives, the doorman tells him that she is on the "troisième étage " and indicates that John should press the corresponding button. John is eventually taken to Roberta on the third floor, which is incorrect since the "troisième étage " corresponds to the fourth floor. In France, the "premiere étage" (first floor) is not the ground floor but the next one up.
