The actress took her eldest sons Maddox, 10, Pax, eight, and seven-year-old daughter Zahara to England's legendary Pinewood Studios to watch Russell Crowe shooting scenes in character as Police Inspector Javert.

Crowe was said to have personally invited the Tomb Raider star, who is in the U.K. to begin working on Disney's Maleficent, to check out the production.
