I have a good feeling about this. It's convenient, and everybody is on Facebook. My only question is how much is it going to cost me. Time will tell.

The social media giant is taking its first step to connect you with movies and TV shows, while collecting a fee in the process. It’s going to let users rent movies directly from the site, using Facebook Credits to pay for the transaction.

First up is “The Dark Knight”, from Time Warner’s Warner Bros.. It will cost 30 credits, or $3, for a 48-hour rental, via an app the studio has built for the site. More movies, along with the ability to purchase the titles outright, are coming.

Warner Bros. describes the rental as a test, but there’s no reason this shouldn’t work. Facebook has 600 million registered users.

Just as important: While other video sites are trying to figure out how to add social “hooks” into their experience, Facebook doesn’t have that problem. It is the social hook.

The only odd thing about this combination is that it’s taken this long to come about.
