Which Europe country is the most successful in film production?

The French scene is quite strong. But lacks diversity, and the level of most actors is just going down. They only based themself on already great actors, but they are getting old.

I think the Spanish are investing in it to become a bigger scene. The English scene might be hurt by the fact that they have the same language than Hollywood, meaning that most successful english actors and staff will be brought to Hollywood and it will be hard for them to refuse.
