Birthday Girl (2001)

Other mistake: In the beginning of the film when John and Nadia are eating supper together, Nadia gives John a ring and speaks in Russian. The camera is at her back so we can't see her mouth move, but it is definately not Nicole Kidman's voice.

Nadia: My name is Sophia.
John: Sophia. Hello, Sophia. Mine's still John.
Nadia: Hello, John.
