IPhone streaming videos to my tv?

I have an iPhone 4S and have already bought a movie through iTunes. I would like to plug my phone into my tv so we can watch the movie on the TV. I only have the charger with the detachable USB cord and I do have a USB plug in on my tv. But it didn't work. So did I do it right? Or is this not possible.

Not with that cable. Go to the Apple website to learn that you have to spend another $60.00 to do what you want.
