Needs a sequel but don't expect it soon
I agree with the people of here that this movie needs a sequel but don't expect it anytime soon. With Jeremy's commitment to Marvel he has a few more years before he's even available to film :(
I hope I'm wrong and he has some free time to film the movie but every other actor(ex Robert Downey JR) has come out and said (or the studios have said for them) that they were booked for a long time and sequels will have to be postponed.
