Too my knowledge, none unfortunately. Most depictions of the fighting on the Western Front in film play up the same old clichés, 'Lions Led By Donkeys', 'Running/Marching into Machine Guns', 'It was all a stupid, futile waste', 'they all fought for nothing', etc. If anyone should correct me here and provide an example of a film that takes a different route, it would go along way to restore my faith in film-based depictions of WWI!

The old WWI film The Battle of the Somme has authentic footage alongside staged re-enactments, but as a propaganda film it is limited in it's ability to portray the wider fighting, a limitation also imposed by the technology of the day.

The best attempt to depict the events of the Somme that I've seen is the docudrama Somme: From Defeat to Victory that was aired in the UK in 2006 for the 90th anniversary. It doesn't skimp in it's criticisms, although it's depiction of the first day is somewhat stereotypical, and it uses the battles for Thiepval in July and September 1916 to illustrate how the BEF was transformed by the Somme Campaign into a effective fighting force.

EDIT: BBC's The Great War episode about the Somme takes a similar view on the campaign, though it's from the 1960s mind you. It is fortunate that John Terraine and Corelli Barnett were the script writers for that episode, as opposed to just someone simply following Basil Liddell-Hart's lead!

Paths of Glory is the only significant depiction of France in WWI that I know of, but it focuses on 1917, and helps to perpetuate a lot of the clichés of what 'everyone knows' about WWI. Watch it for it's story and overall quality, but don't expect to find much of value history wise.

If anyone would care to add, again, it would be greatly appreciated by OP no doubt!
