Tom Hiddleston Reveals Why Loki Was Cut From Avengers 2 (Video)
Darn it all.
Check out the above video where Hiddleston reveals why he was cut from Avengers 2.
Hiddleston says he filmed the Thor dream sequence for one day, but when test audiences viewed Loki in the scene, they figured Loki played a larger role in the movie and was responsible for Ultron.
Hiddleston offers that Joss Whedon and Kevin Feige came to the conclusion that having Loki in The Avengers 2 would be too confusing for people, as it changed their expectations, so they had to cut Hiddleston out.
So essentially the reason for Loki being cut is because he's too popular.
There is also question if Tom Hiddleston will be back for Thor 3 as Hiddleston actually questioned if fans want him back as Loki, and he also said he isn't sure when he'll play the role again.
My response would be that if Marvel thinks Hiddleston and Loki have grown too big -- would be to give him his own darn movie.
