So what is this?

As we headed into Métro Bourse we found ourselves in the viewfinder of a movie crew.  We watched the action for ten minutes or so as the scene was replayed several times.  He was probably shouting, "Get those two women out of here!"  (in French bien sûr!)
For you movie buffs, let me know if this is anyone famous.

You never know what you will discover in the streets of Paris.
