No Loki this time around in The Avengers 2

 
News of the cast-list for Marvel’s upcoming sequel ‘The Avengers’ has been focused on who wil play Quicksilver for the past few weeks, so much so that we didn’t even have time to notice that Tom Hiddeston (Loki) would not be returning.
 
It’s quite common for the villains in this genre not to appear in further installments or sequels (X-Men being the best exception to that rule), it gives the heroes some new challenges and it’s an easy way to spice-up a sequel for fans. While talking on the Empire’s podcast, the film’s director and head writer, Joss Whedon, confirmed that Loki will not be returning.
 
Whedon stated, “I’ve turned in a first draft, but the story is very set. Everybody’s very much on board with the exact movie I’m trying to make which is what worked the first time.” He then continued, “Immitating what I did before is the surest way to do it not as well. Second of all, and Loki is not there to say those terrible things.”
 
The most likely cause for this absence it due to the upcoming Thor sequel, which may or may not put an end to Loki on the big screen for now.
