Which Europe country is the most successful in film production?

Obviously, Hollywood is the most successful in film production. As an asian, I know India, china, korea also get some market share.
But for European country, I don't clearly know which country is the most successful in movie making. I have watch some European movie such as English, Italian, French, German, Russian, Spanish, Portuguese, etc. Except English and Italian, some are just one or two movie I watched.
Because some member of LZ are from Europe countries, they can answer suitble reason.
Please share your opinion, which Europe country is the most successful in film making career?
