10 Movie Roles That Almost Were Cast VERY Differently

10. Margot Robbie as Sue Storm (Fantastic Four 2015)

Margot Robbie is one of the undisputed jewels in the crown of the DC cinematic universe. She livened up the grey and dismal Suicide Squad and has been an absolute joy in Birds of Prey and The Suicide Squad. Long may she reign.

However, things might have been very different had she been cast in Josh Trank's flop of a Fantastic Four film back in 2015. Robbie auditioned for the role of Sue Storm and eventually lost out to Kate Mara. Given how much of a force of nature director Josh Trank was reported to be (allegedly getting into heated physical confrontations with people on set, including star Miles Teller) Robbie's presence would likely not have made much difference to the finished product.

Allegedly butchered by studio interference, the film was a critical and commercial disaster - and no one's crying out for the Trank Cut. Which isn't to say that Margot Robbie can't still give good work in disasters - just look at Suicide Squad.

However, of the Fantastic 4 cast, only Michael B. Jordan appears to have gone on to bigger and better things in both the Creed films and Black Panther. Luckily for Robbie, Harley Quinn was just around the corner.
