I think it was a horror movie showing violent scenes and there's this one scene that has been kinda stuck in my head for like 10 years now so the movie is at least 10 years old.. The scene might've been towards the end of the movie I think and it shows two or more people (maybe a couple) I think male or female not sure it could've been more and they were running from a violent man or a monster they ran towards a store or something, then this violent man or monster gets a hold of one of the people trying to run and then they grab their head and they pour a bad thing (probably acid) in their ear or their face and it's like melting their face or something like that and that's where my memory ends.
Please help me find the movie and don't mind my terrible english
