Three

Three (known as Survival Island in the good old' U.S. of A., which is a horrible title), is best known as that movie where Kelly Brook gets her knockers out. That aspect of the movie absolutely does not disappoint. But as grateful as I am that it provided that vital service, I wish it had at least one other reason for me to recommend it. 

It's basically about three immoral, horrible people who get stranded on an island together after their boat is destroyed, and then proceed to do pretty horrible things to each other. It's not great, but I've seen much worse. Three has a TV movie quality to it, and if you watch it with the appropriate level of expectations, it's not bad. Would I have watched it if Kelly Brook wasn't in it? Maybe. That's more than I can say for most movies that exist solely as an excuse to ogle a really hot woman.
