The actor was linked to the part of Batman before Christian Bale was cast and was also rumoured to be in the running to play Spider-Man.

Asked if he was 'over the superhero thing', Gyllenhaal told ShortList: "At a certain point you realise there's always someone more interesting, talented and ready to do a role than you are - and you won't get every role you go for.
"All I want right now is to hone my skills and become a better actor, not dream about wearing a cape. But you never know."
Of whether his agent was against his five months of training with the LAPD for new movie End of Watch, he said: "It's interesting you say that because [it points out] how the business is taking over any sense of creativity that anybody might have.
"Everyone's going after some goal, be it financial or otherwise and, in my perspective, that is totally out of whack. But no, I wouldn't work with an agent like that."
