I need to get a purchased movie off my iPhone and onto my computer! How do I do that?

So, yesterday I purchased and downloaded a movie onto my iPhone from the iTunes Store and unfortunately I only have 16GB of storage on it and the movie is large and threw me pretty close to full. I'm wondering if there's any way I can sync my phone to where I can keep the movie on iTunes on my computer but not on my phone. This morning I synced my phone but nothing happened, with the movie I mean. I still have it on my phone and I don't even see it on my computer.

If it helps I have the iPhone 5C running iOS 7 and iTunes 11 (11.1.4.62)
Any help would be incredible!

Open iTunes, sync your phone, and then go to the movie library. Once there click on file > transfer purchases…

That should download your movie onto iTunes.
