When will league get a movie?

Ok, seeing this WoW bullshit going on the big screen I started to think that league should get a sequel. Now I know video game based movies don't get the best ratings on IMDB or rotten tomatoes but don't you think that riot can make something that can give it a above average to average rating? I mean LoL is a huge game, and money for their budget can exceed well over 90M+ dollars. A new dawn sparks the main idea for this. Whats your opinion? should riot ever think about making a movie or should it be an idea that they should never consider?
