I was at the Canadian Resort while they were filming this movie
8 September 2005 | by nltgobillsSee all my reviews

I was present at Delmonte in the Pines resort when they filmed this movie. My parents took us there every year. It certainly was no great film, BUT we got to see the actors and the old resort house/area and boat house area in between filming. I was a kid, 9 years old, but I remember seeing dobermans in large fenced areas for the movie and the actor who played "Humongous" was sooo tall, but very nice. They did actually blow up an old boat house out on a little island. When they did that, I was going to bed in the new resort area and remember being afraid of the noise, and the filmed "screaming" from the movie being shot. For a low budget film, it was totally cool to see the remains after the shoot, the old boat house, the props left behind and they ripped an entire floor out of the old resort main house, and there was "blood spatter" etc. in it. That was truly a cool experience.
