I also wouldn't consider Dead Snow to be a comedy, but a relatively low budget but really good zombie horror movie.I don't recall Dead Snow (great movie) being a comedy and Dead Snow 2 was just bad.
Great ideas! For a mask joke you could also rip off Robert Stack, in I think one of the Airplane movies, when he pulls off his sunglasses and has another pair underneath them.I'm thinking of making one called 'And the year was 2020'. It will be a montage of news clips from deserted metropolis streets to crowded rioters to cardboard fans-in-the-stands. Have not decided on the sound track yet. Some Monty Python bits ('run away'), alternate screaming/crying/hysterical-laughter. Jaws theme will probably be on it. Flight of the Valkyries would work. Lots of material and we still have an election and another flu season to get through.
