Trying to find out 70/80s movie name
 

Hi,

I took some sneak peaks at a movie when I was a kid in the 80s, I suspect the movie was either form the early 80s or the 70s.

The movie really made an mark on me as a kid but I was never able to find out its name, maybe someone will be able to identify it by the plot that I remember:

I remember that the movie started in a cinema where, if I recall correctly, a mask was in exposition in the lobby as well as a bike. A few friends play around with the mask and one of them places it on the face. The mask makes a small cut, and later when they are watching the movie this person goes to the bathroom and something nasty happens, some sort of infection starting from the cut. I don't recall if that person turned in to a zombie but it was mayhem from then on.

Anyone is able to guess this one?

Demons [1985]

Fantastic! :)

That is definitly the one I was looking for. I'm going to have a lot of fun viewing it again. Thanks.
