If this is the cast we dont think any D.C comic fan would be disappointed with this Sucide Squad. 
Ayer's Suicide Squad is still in early development and the script is being worked on. But that is not stopping the filmmaker and the studio from making overtures for what is to be an A-list ensemble piece filled with colorful antiheroes. Sources say that Will Smith, Margot Robbie and Tom Hardy also are fielding offers. Warners had no comment.  

Tom Hardy has won hearts all around the world with his performance in Dark Knight Rises as Bane, and he will definetly be able to provide justice to other iconic characters like Deadshot and Captain Boomerang. Margot Robbie might get considered for Harley Quinn. Even Will Smith has done superhero movie Hancock

Unlike most other actors in his age group, Gosling can be especially choosy. He has said no to superhero fare before due to his desire not to be tied down to future movies. For instance, Gosling was keen on taking the role of Hal Jordan in Green Lantern, but balked at a contract that called for sequels. 

Even when he does a studio movie it’s not the usual fare, instead opting for projects such as Crazy, Stupid, Love and Gangster Squad — both for Warner Bros. — for which the chances of sequels are small. So he is least expected to sign this film from the above names
