with the horrible events yesterday in Moscow.. The event made me think of a specific movie I saw within the past few years.  The opening was I believe in France on a concert stage with the auditorium filled with middle aged adults in suits and gowns listening to either an opera  or a Play. 

All of a sudden a group of terrorists invades the theatre with machine guns and bombs .  I can't remember which movie this was from..

any help or ideas ,, ?  I keep thinking a movie like mission imposible  or maybe a marvel movie..?

Thanks
