One could start this theme (if it's welcomed) with this example:

In this excellently remastered version of Feuillade's silent crime series of 1915 (of which I am a great fan), composer Robert Israel created an excellent soundtrack, made of (orchestral) arragements and pastiches of different Romantic pieces (including the theme of Alkan's Etude VIII, op. 39 as a main title and thorough leitmotif). The 10th and 12th episode of this series has Raff's Adagio from "Lenore" as an accompaniment of paceful family life scenes.
See also IMDb (http://www.imdb.com/name/nm8867222): some music by Raff was used in the film Downtown Express (2011) (not sure what, though- has anyone seen the film?)
Oh well, it's the Cavatina (track No. 3 of the soundtrack disc):

Speaking about the Cavatina, in this album we can hear Debussy's transcritpion of Raff's piece:

(suppose these discoveries are also in the complete Debussy CD edition by Warner)
It's always the Cavatina! The piece on the Debussy set is his piano arrangement of the piano four hands Humoreske in Waltzform. It's a pretty piece, but not particularly well played unfortunately.
Oh yes, sorry, Mark, for my mistake :-(
Good enough, since there are already enough arrangements of the Cavatina around...
There is a 1993 romansh (rumantsch) movie, an unhappy love story about two young people who have ben left unaware that they are in fact brother and sister. It's called ,,Levzas Petras" (Bitter Lips) and uses the lovely main subject of the slow movement of Raff's Spring Symphony, No. 8.

Thanks, britishcomposer :-)
As a Swiss, I should have had perhaps an idea about this movie...
And to those members in here, who do not know what "rumantsch is, we should explain that it is our 4th national language :-)
Ah, what I we called "Romansh" back in school days!
