Should Warner Bros. eventually decide to proceed with a film adaptation of Harry Potter and the Cursed Child, original Harry Potter director Chris Columbus has been outspoken about his desire to tackle the project. Columbus, who helmed the first two films in the franchise, has revealed that the idea of reuniting with the original cast for a new film is actually “a small fantasy of mine.”

Yet while Columbus may be keen for such a reunion, not all the original cast members are similarly on board.Though Draco Malfoy actor Tom Felton seems keen on returning to his role, the potential involvement of the franchise’s three lead actors, Daniel Radcliffe, Emma Watson and Rupert Grint, is less sure. While Grint has previously explained he would only return if everyone did, Radcliffe has made it clear he is not yet ready to return to the role of Harry Potter.

Presently, it seems there are many barriers to getting a Harry Potter and the Cursed Child film together, but only time will tell if they can be overcome.
