You may be surprised to see some movie titles that you don't think of as "French" movies, even though you have clearly selected the "French" language.
Why is this happening? Because many movies these days come with alternate language tracks that allow you to see the movie, but hear it in a language other than the one the actors originally spoke.
This is not necessarily a bad thing, just something that you should keep in mind when browsing movies by language. And you can always still practice your French by watching Moneyball dubbed in French!
