When you get the roll of film to use it you must teleport back to where you upgrade your gun. You should say the projector displaying on the tv, hold square or x on the xbox 360 on the projector and it will change the movie shown. There is more than one roll of tape, and one more easter egg is the music.
To turn on the music simply find three stones, one in the room where you start out, another one where the top of the alley is, and the last is the room where you find the mp5k. After that a song will be played wjile you fight zombies.
With the film if you teleport again hold square and a video will show up on the screen.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
