Sysselmann is described as "a stout, fussy man". Does that sound like Harry Potter's cousin? We think so!

In fact, His Dark Materials does share some similarities to the Harry Potter universe, as it’s also an epic fantasy novel series that follows children on a spellbinding adventure. So a must-read for fantasy fans everywhere.

If you’ve been watching the latest The War of the Worlds adaptation, you may have seen Harry Melling pop up there too. He plays the Artilleryman in the new BBC1 series, based on the H.G. Wells novel.

As one fan joked, we’ve just been Double Dursleyed! You might not have noticed either…
