Depending if its a smash hit (which it will be) I would like to see a sequel, primarily set in the 80s, with Scott, Jean, Ororo, & whoever else as a 5th student in the next.
the sequel should focus on Xavier/Beast/Moira continued working on the school & human/mutant relations
intro. the Danger Room
Scott, Ororo would already be there as Jean is the new recruit,sort of (Xavier had weekly sessions w/her, but Jean decided to stay on at the mansion when Xavier felt as if Jean no longer needed his help)
There can be a scene were Jean tells Scott about her childhood & Scott his thus starting the beginning of their relationship
in TLS it looked as if Storm & Beast were good friends, so maybe it could be a scene where Storm shares how she was treated as goddess w/Hank and how she faces prejudice in USA
from the spoilers I read it seems that some go w/Magneto, but I don't think the
Brotherhood should not have much focus since the 1st film is kind of "their" film, but I would like to see Mystique acting as liason for Magneto(who role is smaller) her role would be similar to X1 & X2 i.e spying on Xavier or government
if Havoc is "around" then I would like to see his relationship w/Scott played out
Also from what I read about the 1st film, I could see Xavier being reluctant to let his new team fight, but eventually he realizes that the world needs to see mutants in a better way and after the "events" he realizes he assemble a good team
for the villains I'm thinking more of the government, hm Project Wideawake, intro. Sen. Kelly, Bolivar Trask or Stephen Lang also an idea for TLS was to have a battle in Washington DC, so I would like to see the Brotherhood lead an attack in D.C. and tyring to assinate the Pres.
a scene that would kick ass if Xavier lets Jean true power show in order to save the world(just like in Ult. X-Men)
I'm not sure about Emma Frost, but I would like to see her do a 180 like in the comics, start of as a villain, and becomes good in a sequel(or maybe she's after Jean) her character cannot be a 1 time only!!!!
anyway just some ideas I had for a sequel if I come up with some ideas for a 3rd film I'll post em...
