British actor Alan Rickman has died at the age of 69 from cancer, his family confirmed on Thursday.
The stage and film legend was beloved for his roles in Die Hard, Sense & Sensibility, Robin Hood and Galaxy Quest, but is most famous for his portrayal of potions teacher Severus Snape in the Harry Potter films.
Snape is perhaps the most misunderstood of all JK Rowling's characters.
His complex relationship with Harry Potter is central to the series and is not fully revealed in its final moments.
Fans of the books and films had the potions professor's backstory teasingly revealed in flashbacks, but enterprising YouTube user kcawesome13 rearranged them in chronological order to create a fascinating insight into the character that fans will enjoy today more than ever.
Be warned the below clip, which helps to explain why Harry described Snape as "probably the bravest man I ever knew", contains a lot of feels.
