Ok, so there’s this horror movie I’m looking for. I remember barely anything from it. I’d say it was from between 2010-2014 and I AM NOT SURE but I think it happenned in a foreign country (but is an american movie). I saw this movie in french in my Canadian movie theatre so it means it got an international release. The only thing I remember about it is that the main vilain is a kind of black fog with orange electrecity in it. It kills people. The main characters are a group of adults. There is a scene where they all are outside and the black thing kills a dog near a bridge. I am not sure but I also think this movie is found footage! The movie is not Chernobyl Diaries. Thank you for your help!
