Does anyone know this movie?

A movie about two guys that escape from a police car and hide in a house but there lives a crazy family. When they get in the house one is dripping blood. They also forget someone in a car trunk. And mom kills the maid. A lot of people die but the two guys are really innocent. There is also a band of four walking around singing. I think the movie might be french not sure.

Thank you but its not that movie i also remember one of them is leaking blood when they first enter the house and the movie is more like a dark comedy.

doubtful, but “bloody hell”?

older, but “cul-de-sac” seems close

Thank you for trying its really similar like two wounder come to the house but they are crazy in another way. Appreciate your effort.
