While Marvel Studios may not be putting out a Loki movie anytime soon, a fan has gone and created the following film starring Tom Hiddleston as Thor's trickster brother.
The Loki movie below uses footage from Thor, The Avengers and Thor 2.
It's not presently known when Loki will next make an appearance in the Marvel Cinematic Universe as Tom Hiddleston has stated on a few occasions that Loki will not be in The Avengers 2. Thor 3 is currently being written, so more than likely he'll be appearing there.
Tom Hiddleston currently has four movies in development including Crimson Peak, which hits October 16, 2015.
