Harry Potter 'fans' have taken to Twitter to mourn the death of Ian McKellen, AKA Gandalf, after confusing him for Sir Christopher Lee, who passed away on Sunday.
McKellen played the Good Wizard in the 'Lord of the Rings' films, alongside Lee who was cast as the villain, Saruman.
The news of Lee's death was announced on Thursday morning. He died at the age of 92 at London's Chelsea and Westminster Hospital, where he'd been for several weeks.
The veteran actor's work spanned seven decades, including roles in 'James Bond' and 'Lord Of The Rings'.
