The M4 SMG aka Spectre was noticed in the first person shooter game Call of Duty: Black Ops. I just happen to notice that same machine gun in Leon: The Professional. Here is the clip!
Leon/The Professional, (along with La Femme Nikita) inspired the creation of a full length ऐनीमे movie called "Kite". This ऐनीमे flick in turn inspired the concept for No Doubt's संगीत video for "Ex-Girlfriend".
