One of the things I love about Beethoven's music is that it feels so timeless. By that, I mean that B's music feels like it could fit with today's world very easily. And by THAT, I mean that it can be used in modern film soundtracks. In fact, it according to IMDB, B's music is used quite alot in film and TV. There are 474 entries for Beethoven, not including actual concert films. Many of these uses are as "source music" (music actually played on screen) so are not necessarily film score in the strictest sense, but there are cases where its use is so effective it actually makes scene worthwhile (though perhaps not the whole film..).
Here's IMDB's Beethoven listing.
And here's a recent and very memorable use of the Allegretto 2nd Movement from the 7th Symphony. It's from the end of the film "Knowing" so if you don't want to know how it ends I'd recommend watching the film first. Its not a terrible film (but could have been better).
Here's String Quartet Opus 131 - Adagio quasi un poso andante, as used in the episode "Why we fight" from Band of Brothers. Almost brings a tear to my eye....
And apparently String Quartet in C Minor, Op. 18 No. 4 was used in "Mission Impossible III" and the Kreutzer Violin Sonata Op. 47 was used in "Hellboy II - The Golden Army". Good luck with your mission if you choose to accept it.
I hate to give the impression that B's music is used in sub-standard films but apparently modern producers are not very familiar with the Coriolan Overture or the Egmont stage music. That music would fit right in with a Ridley Scott film....
...Putting money where mouth is, here's my quick attempt to put B with Tolkien and Jackson:
(I know it's not perfect, but I need to leave some work for me to do when Hollywood calls me up and hires me to score all their movies, right? FYI - I used the allegro from the Pastoral "Storm" movement and an edit of the Coriolan Overture)
