According to Variety, Michael Keaton (Birdman, Batman) is in negotiations to play the villain in the film.
Tim Burton (Edward Scissorhands, Corpse Bride) is directing the film, and if Keaton joins, this would be their first film together since 1992’s Batman Returns.
The mouse instills into Dumbo the idea that with the help of a magic feather, he can fly.
Keaton would play the person who buys the circus from DeVito’s character to use the flying elephant for profit.
