<P> Abu - Assad has said of the film, "I really didn't see an epic love story against the background of survival, I think optimism and hope is crucial to survive . And to go on with your life even if you've had a lot of bad luck . So if you give (in) to the bad luck, you will die . (But) if you fight the bad luck, you have a better chance to survive and make your life better . This is very simple wisdom, yes? But still very crucial especially in these kind of days, when everybody feels entitled to their good luck ." </P> <P> The film went through several lead casting changes . In March 2012, it was announced that Michael Fassbender would star as Bass, but by September 2014, Fassbender dropped out due to a scheduling conflict, and Charlie Hunnam replaced him .
