Two English dubs?

Watching the trailer, I became really intrigued with this film. I picked up the US DVD released by Severin and noticed that the dubbing is much different from the trailer. There are many hee-larious lines of dialog in the trailer, and the lack of them in the film really bugs me.

Is there an older English dub for the film, or perhaps is one a UK dub and the Severin DVD a US one? Or is the dubbing on the trailer exclusive to the trailer?

"Your kiss is cold and icy as death; your embrace, deep as the night."

"I'm dying to sleep with him! I can't wait till tonight! I wish he were here now!"

These lines and others are so much better than what I'm hearing in the film. There's a certain quality to the dialog and deliveries that is really intriguing (and funny).
