After witnessing grand success with La La Land, director Damien Chazelle is set to bring a historic film, Babylon. However, media reports have claimed that its lead actor, Emma Stone, has been replaced by Suicide Squad actor, Margot Robbie. Reports stated that Emma declined the film after having lots of projects in her kitty. Hence, Margot was chosen as the leading star. Though, talks are in process with Margot. If Margot accepts, she would be working with Brad Pitt for the second time, after Once Upon A Time in Hollywood.
