There's a scene of a wizard reading "A Brief History of Time" in the movie, Harry Potter and The Prisoner of Azkaban. The wizard looks like Joe Dempsie.

Here is a snippet of Game of Thrones season two that show Joe Dempsie as Gendry.

Still for easier comparison

But his filmography list does not mention any Harry Potter movies, and nor does his IMDB page.

If he were in the movie, he would have been 16 or 17 years old when it was filmed.

Is there any evidence to suggest that the wizard reading "A Brief History of Time" is Joe Dempsie?

    FWIW, in my opinion Ian Brown (the actor/musician) who made this cameo, also bears a strong resemblance to Liam Gallagher of Oasis and even a bit like Jason Williamson of Sleaford Mods. In general, that overall male “look” and bone structure seems to be very common in the U.K. So fair mistaking one for another but just wanted to add my two cents on others as well. Jan 22 at 3:18

I've never thought of Joe Dempsie being that wizard (just because I can't see any similar facial characteristics), and I originally found that information on a Harry Potter fandom: it's Ian Brown.

He's also pictured as this wizard on his IMDB page and credits :

From comments
For those unaware, Ian Brown is not an actor. He was lead vocalist with a band from the late 80s/early 90s, The Stone Roses, who were a major influence on a lot of the Brit Pop movement of the 90s. This music scene in the UK was known as "Madchester", a portmanteau of Manchester, the city many of these bands originated, & a local term for 'I really like this', "I'm mad for it".
By a series of coincidences, Brown knew a girl who knew the director… & it happened that Daniel Radcliffe was a fan, so he managed to 'blag'* a cameo.
Possibly because they shared a music scene, a fashion style, a geographical & musical origin …& also knew each other well, Ian Brown could often be mistaken for Liam Gallagher from Oasis -

*Blagging, in the UK , especially inside the music or film industry, is not to gain something by deception, but to gain entry to somewhere or something you wouldn't ordinarily be invited to by 'knowing someone who knows someone who can get you through the door'. The US equivalent may be 'schmoozing'.

Culturally, you could consider The Stone Roses to be as important to the history of music in the UK as Nirvana were in the US.

    All those Manchester bands of the era share a similar set of gestures & facial expressions;) At first glance I thought it was a Gallagher, but yup, you're absolutely right, it's a 'stone rose'. I'd honestly never have noticed.

    Like peas in a pod - I thought a picture of the two of them together wouldn't be too hard to find… i.stack.imgur.com/fRulS.png
