However, please note: Mark Rylance hasn’t been cast as Dumbledore yet! In fact, there have been no negotiations between HBO and the actor at this point.
Instead, Rylance is at the top of HBO’s wish list for Dumbledore in the Harry Potter series, while they have already put out feelers about his interest and availability.
If Rylance, who won the Oscar for Best Supporting Actor in Bridge of Spies, actually becomes Dumbledore, he would be the fourth actor in the role. Previously they brushed against each other Richard Harris (Harry Potter 1-2), Michael Gambon (Harry Potter 3-8) and Jude Law (Fantastic Beasts 2-3) wear the wizard’s robe.
