Phone call?
I love this movie! I rented it for two reasons -- first, it sounded interesting, and second -- Patrick Muldoon. I think he's gorgeous, and he's an awesome actor.
The ending blew me away -- on a second viewing I realized it was somewhat obvious -- but fun nonetheless.
:::SPOILER WARNING:::
My only question is -- who called him in the beginning? He couldn't have imagined it since his roommate was right there, and the roommate was not his imagination. Any ideas? Or is this just a goof?
