Son Of Batman was a pretty decent animated film in my opinion it had some cool fight scenes and the animation was good. It did lack in some aspects like the plot of the story. The story could have been better and would have been a little bit more interesting if Barbra Gordon, Jason Todd and Tim Drake were in it. The best animated film was Under The Redhood in my opinion some might disagree others will agree. Below is my fancast of Son Of Batman.
Richard Armitage as Batman (Bruce Wayne)
Richard Armitage has the acting ability as well as the intimidating presence required to play Batman. He was one of my contenders to play Batman, Luke Evans and Joel Edgerton being the others. Armitage can be seen in The Hobbit movies and Strike Back.
Isaac Hempstead Wright as Robin (Damian Wayne)
A young actor from Game of Thrones, he is a pretty decent young actor who could be a fine Robin.
Manu Bennett as Deathstroke
The Slade in Son of Batman was not like Manu Bennett but I think he was rather lame so I went with Manu Bennett anyway since he is a badass on Arrow and Spartacus
Lena Headey as Talia
She is a good actress who has the look and acting talent to play Talia.
Matthew Wilig as Ubu
A tall and muscular actor who kind of looks like Ubu is he was bald.
Alex Russell as Nightwing (Dick Grayson)
A talented young actor from Chronicle, Carrie and The Host. He can pull of Nightwings personality and I think he would be a decent choice for Dick Grayson if he ever appears on the big screen.
Bryan Cranston as Jim Gordon
A good actor who has been in many suggested many times as Gordon. He also voiced Gordon in Batman: Year one.
Sean Bean as Ra’s Al Ghul
A damn good actor who would nail this role. He has been in Game of Thrones, Troy, Lord of The Rings and Equilibrium.
Timothy Dalton as Alfred
A popular choice for Alfred before Jeremy Irons was cast.
Doug Jones as Kirk Lanstrem
He has the built and acting ability required.
