Batman Vs. Superman has nutritionist and fitness expert Rehan Jalali on its side, as he trains Ben Affleck for what could be the role of a lifetime. He is getting the actor ready to play Bruce Wayne's vigilante alter ego, and he's not going lightly on the Oscar winner, promising that this Dark Knight will be large and in charge.

That's not to say we're getting Fatman instead of Batman. Rehan Jalali previously worked with Ben Affleck on the 2010 thriller The Town, and they have a good working relationship. What Rehan wants to bring to the movie is a 'real life' superhero look, as we might see them on the street, not in the pages of a comic book or in a highly stylized movie.

In a series of Tweets, the workout expert explained what he and the actor are shooting for in terms of a lean yet legendary body type.

What are your opinions on this? Is this the type of Batman you were hoping for? Or is Ben Affleck himself still a deal breaker in your opinion?
