Can I use icloud as a way to be able to download more videos on my iphone 5?

I have an ultraviolet account, I mainly use it on my Flixster and Vudu apps. Flixster gives me the option to download the movies on my iphone without having to use Wi-Fi so I can watch it anywhere. The problem is that the movies take up space and I need some on my phone obviously. I was just wondering, since I have unlimited data and i'm using icloud now, is there anyway i can store the movies on my icloud and still have leftover space for other things in case I download a good amount of movies? Or can icloud help me access my downloaded movies anytime without using Wi-Fi or having to stream it? I just want to be able to watch my movies anywhere I please.
