Some fans on social media have suggested that the wizards scar was shaped like the hand motion to cast Avada Kedavra - the infamous killing curse often used by Harry's arch enemy Lord Voldemort, who was the person that originally gave him the scar.

In a post, they shared a screenshot of the Harry Potter wiki and wrote: ''Did you know Harry Potter's scar isn't a lightning bolt, but actually the hand motion to cast Avada Kedavra.''

Fans couldn't hide their shock at the discovery, with one tweeting: ''I'm not even a Harry Potter fan and I'm surprised af.(sic)''

Another said: ''It all makes sense now. (Sic)''

A third added: ''I actually didn't know that, I loved the movies but never read the books or really geeked out on it. (Sic)''
