Hey people, I'm sure I watched twice a horror movie from the early 90s, set on a castle during a masquerade ball/costume party, where people starts to get murdered,the main character was a Blonde girl with curly hair and I remember that on the plot her ex-boyfriend was a character named Max and there was another character named Colette, I'm 90% sure that this was an australian movie (unless I am mistaking the information on the box with some other movie) and searched google many times to find out the name of this movie, but so far, I haven't reached a single information about it; has anyone on this page ever seen this picture?
Has anyone, any clue about this film?

I REALLY would LOVE to watch it again, it has been 17 years since I watched it, but I don't have the slightest idea about the moive's name and it seams impossible to find any info about it, if anyone knows the movie I'm talking about and it's name, please reply to this comment.
Thanks.
