ok guys,
i've got this movie in my head without a title and everyone thinks i'm just crazy. The movie is a comedy about this group of people (going seperatly in couples or families) on vacation. The end up at this (haunted) castle. One of the major parts i remember is when they are watching this theatre production abuot a ship at sea, and the whole thing comes alive, and i'm sure it involved an octopus/squid. it seems like it was an early 80's or even late 70's movie, but i'm sure it didn't come out in the 90's.
also, i remember watching it on tv as one of those saturday afternoon movie things. give me any and all ideas, i just don't want to not know what it is anymore and prove i'm not crazy.
