Rumors are flying faster than a Firebolt that Warner Bros. might make the play Harry Potter and the Cursed Child into a movie and they want Daniel Radcliffe to don the wire frames again. The biggest problem with this — aside from all the canon divergences — is Severus Snape.

In the play, Harry’s son Albus and Draco Malfoy’s son Scorpious team up to screw around with time-turners because they apparently never read Prisoner of Azkaban or even saw Back to the Future. Shenanigans ensue in the form of several alternate timelines.

In one, Voldemort rules the world, Harry is dead, and Ron, Hermione, and a still-living Snape are part of a rebel movement.

The problem, of course, is that Alan Rickman was among the tragic “gone too soons” of 2016.

If Daniel Radcliffe didn’t appear again as Harry, that would make sense, considering the fact that he is not a man in his late thirties and early forties trying to accomplish that with middle-aged makeup didn’t quite have the intended impact in the Deathly Hallows epilogue.

But Alan Rickham is so singularly Severus Snape, it would be impossible for anyone else to step into those shoes. If a Cursed Child movie happens, it would do well to remember that. Always.
