7) Will Poulter
An actor of Monaghan’s age group would certainly be appropriate for this project. Seeing as it will depict Joker’s origins story, it could easily cast the character as a young man in his twenties, and if this is the direction the film goes in, it would be a very different portrayal of the villain from those we’ve seen on the big screen before. Instead of the established names that have previously played the Clown Prince, then, an upcoming talent should be awarded the role.
Following this train of thought, 24-year-old Will Poulter comes to mind as an excellent candidate. The British actor’s star has been on the rise for while now, as he’s made his name in kid-friendly franchises The Chronicles of Narnia and The Maze Runner over the years. However, in his more mature roles – e.g. The Revenant, Detroit – he’s proven that he has the chops to go darker. In fact, Poulter was once linked with the part of Pennywise the Clown in It.
Perhaps the best reason he should be considered for the Joker, though, is that Poulter has said he’s always wanted to play a Batman villain ever since watching Heath Ledger in The Dark Knight.
