Do you know which movie is this?

I didn't watch the complete movie, just the scenes at the beginning. It starts with two kids asking their mother to tell them the story with spies before going to sleep; so, she tells them about a female and a male spy who worked for different countries. They were given the task to kill each other and so on. When the mother exits the room, she sits on the dressing table and the father of the children asks her which story was she telling them to which she replies "Our story". Then, both of them press some buttons on the tables they were using and the room changes into a very high-tech something. I was unable to watch the rest of the movie but i want to watch and don't know the name. So, please help........
