I want to find a certain movie! The movie centered around a gathering of people attending an event at a castle only to be locked in.

This movie seemed as if it was made during the 80's. I believe that the people were wearing Halloween costumes.

All exits were barred, and the main entrance was blocked with a metal gate. I think that only a woman and a man survived this tale.

Does anyone remember the title of this movie? Any help would be sincerely appreciated.

Thank you.

Try night of the demons

I think this movie is called Hell Night. It has Peter Barton and Linda Blair.

I appreciate the replies, but the movie was not Hell Night or Night of the Demons.

This movie could be demon house aka night of the demon
