He said he is up for movie roles. But he admitted that he has not read Marvel Comics before as he was always a DC guy even before he became a DC guy. Amell added that if he is offered an awesome Marvel superhero, he would not hesitate to accept it.
Fans and critics of Marvel Cinematic Universe believe that the best that Marvel can offer to Amell to play a superhero role is the villain-turned-good-guy Nighthawk. They also think that Stephen Amell could also play a role in the upcoming sequel of “Guardians of the Galaxy” or he could also play the role of the Punisher.
For a very popular actor in the DC TV universe, it would really be far-fetched for Stephen Amell to take on such second-liner Marvel superhero characters. The only way Marvel can pull him out from DC is if he is offered a popular Marvel character. Anything less would come out as almost an insult.
With that being said, it is unlikely that Amell will leave “Arrow” after Season 4 because staying on the TV series offers him the prospect of taking his character to the big screen in the distant future, especially now that Warner Bros has already committed to expanding the DC Cinematic Universe in the movies starting with the upcoming showing of “Batman vs. Superman: Dawn of Justice” due to hit theaters on March 25, 2016.
this is not completely accurate tho. Digg already have his alter ego. He become “Spartan” and I´m pretty sure they´ll give Felicity a brand new alias. lets see… they could make her Oracle, or maybe just use some Oracle storylines… they will make Calculator her father. who is a Oracle/Birds Of Pray villain. or maybe Proxy (Calculator´s daughter. Also a tech genious)
