William Castle really excelled at adding a showman's flare to fairly routine genre fare. Here you have a group of folks compelled to spend the night in a haunted house. You've seen it many times before, and you'll see it many more times. But Castle's films are so damn entertaining that it just doesn't matter if the ground isn't fresh. His approach always is.
What do you get if you mercilessly rip-off "The Wedding Banquet" and then add a big dose of "Play It Again, Sam" to kind of hide the fact? This. Only in true Canadian film industry fashion, none of the actors are really good enough to pull it off. Kyle MacLachlan is the big name they pulled in and if I never see him do a Cary Grant impersonation again, I can truly die a happy man.
