EON productions, who are the producers of the official James Bond film series are notoriously protective of their property and rarely give permission for clips to be used in other studio's movies for fear of the clips being misused or lampooned. In this case Dame
Helen Mirren and director
Roger Michell personally asked the Bond producers
Barbara Broccoli and
Michael G. Wilson for permission to use the Scene from
Agente 007 - Licenza di uccidere (1962) and promised the scene would be used in context and not adulterated in any way. A small fee was paid (which was donated to charity) and Broccoli and Wilson were allowed to view the finished film with the promise of that if they didn't like how the scene was used then it would be removed before release. Fortunately, they had no complaints.
