Help a Newbie?

I saw a trailer here on twitch a while ago. It was for a WWII zombie movie and can’t remember the name.
It wasn’t a North American made movie. The syle was kind of that gritty-washed-out-colour-type. There was no dialogue.
I’ve tried looking through the archive, but no dice.
In the trailer:
It opens with 2 boys in a field (by a creek?), they are walking along and stop and look up to stare at something off camera . The shot widens to reveal a tree and it is slowly revieled there is a dead (German?) paratooper hanging from it. Then they look up and see the sky filled with parachutes-presumably zombies.

Anyone have an idea which movie this is?
It kind of freaked me out and I loved it!

Thanks for your time,
Shane

you have seen the Cannes market promotional trailer for “Worst Case Scenario”
http://www.gorehoundinc.com/
(it’s called CGI trailer now on their website). The film itself has not started shooting yet. There are long silent pauzes between news bits. Last was of Februari claiming that shooting would start this year. The talent is there, the trailers look good, but financing seems to be difficult for a project like this in the Netherlands / Europe.

That’s it!!
My memory of the details was a bit off, but it still looks awsome.
Would love to see it when it comes out.

Thanks petcor80!!
