"Harry Potter" alum Jason Isaacs weighed in on the online controversy surrounding Paapa Essiedu's casting in the upcoming HBO series adaptation.

Jason Isaacs, who portrayed Lucius Malfoy in the original Harry Potter films, has spoken out in defense of actor Paapa Essiedu, who was recently cast as Severus Snape in HBO’s upcoming Harry Potter series.
