When Patricia addresses Chris (Richard Harris) as "Richard" during the William Shakespeare scene, she is referring to his impression of Richard Burton.
As Christopher and Patricia are touring the TV commercial studio, the director calls one of the actresses Mandy (as does Patricia later on), but in a later scene in Christopher's house, he calls her Miranda. Mandy is understandable as a diminutive for Miranda.
When Patricia follows Su home, she finds Su living in a luxurious house in the hills, complete with pool. The next time we visit Su's home, it's a high rise apartment.
A policeman says that Patricia cannot be prosecuted in France for industrial espionage, but only for "simple robbery." However, the crime of robbery involves the use or threat of force or violence; stealing corporate secrets would normally be larceny (theft), not robbery.
