By watching films and TV shows featuring the new Harry Potter cast, fans can get a better idea of what to expect, and when they see the cast's talent, their anticipation for the reboot will hopefully rise.

10 Harry Potter Characters Whose Names Hide Secret Meanings

6 Janet McTeer In The Menu

Janet McTeer Will Be Playing Professor McGonnagal

The Menu is a fantastic film, which Harry Potter fans should watch regardless, thanks to Ralph Fiennes' terrifying role as a chef, which is somehow more haunting than his portrayal of Lord Voldemort. However, with Janet McTeer also appearing in the film and having been subsequently cast as Minerva McGonagall, fans now have another reason to check it out.

In the film, she plays a food critic in a fairly comedic role, which shows promise for those rare but magical McGonagall moments where she lets her stern facade down. For more in-depth looks at Janet McTeer's work, fans could try watching TV shows such as Ozark, Sorry for Your Loss, and MobLand​​​​​​. These examples will prove to fans that she can easily pull off Professor McGonagall's intimidating side.

5 Paapa Essiedu In Gangs Of London

Paapa Essiedu Will Be Playing Severus Snape

Paapa Essiedu will be taking on the tough role of Severus Snape, and for those looking to get a glimpse of what to expect from the rising star, there are thankfully plenty of options to watch. While Paapa starred in the Lazarus Project, some of his best work outside of theater was arguably his highly dramatic role in Gangs of London.

Harry Potter has proved himself as a talented wizard thanks to his use of powerful spells in and out of Hogwarts that have rivaled even Voldemort.

His incredibly tense scenes in the show, sometimes when complicated love is involved, should get fans excited for the later seasons of HBO's Harry Potter, when Snape's tragic past and present come to the fore. For a completely different look at Paapa Essiedu, fans could also check out the Demon 79 episode of hit show Black Mirror, where he plays a demon in training.

4 Dominic McLaughlin & Nick Frost In Grow

Harry Potter Dominic McLaughlin & Nick Frost

While the upcoming Hagrid actor Nick Frost may not need any introduction, having starred in popular films such as Hot Fuzz and Shaun of the Dead​​​​​, fans will be eager to see the work of the newly cast Harry Potter himself, Dominic McLaughlin. Thankfully, there is a family comedy film called Grow coming out featuring both of these actors.

Funnily enough, this upcoming Sky Original film is about growing pumpkins, something Hagrid is known for. While the extent of Dominic McLaughlin's role in it is currently unknown, fans will also have another opportunity to witness his acting talent in Gifted, an action-adventure series for kids set in modern-day Edinburgh. Interestingly, this series will be about young Scottish teenagers who have superpowers not that dissimilar to those of wizards and witches in Harry Potter​​​​.

3 Paul Whitehouse In The Fast Show

Paul Whitehouse Will Be Playing Argus Filch

Interestingly, Paul Whitehouse's new role as Hogwarts caretaker, Argus Filch, will not be his first in the Harry Potter franchise. He was cast as the portrait of Sir Cadogan in The Prisoner of Azkaban film, and can be seen in a deleted scene.

Outside of this brief appearance in the wizarding world, fans will best be able to get a sense of Paul Whitehouse's incredible range and comedic genius by watching clips of The Fast Show, a sketch show from the 90s where Paul played many weird and wonderful characters.

2 John Lithgow In The Crown

The Crown Winston Churchill Cropped

If fans have any concerns about the American actor John Lithgow being able to pull off a British accent for his role as Albus Dumbledore, they should watch The Crown​​​​, a fantastic show in its own right. Alongside a star-studded cast including Bellatrix Lestrange actress Helena Bonham Carter, John Lithgow delivered an all-time great performance as Prime Minister Winston Churchill in his post-war years.

Headmasters & Headmistresses of Hogwarts are very much hit or miss; here are the best and the worst of them.

While John Lithgow has featured in many other great films and shows over a long career, including some favorites such as Shrek and Dexter, one of his latest roles in Conclave is another great watch for Harry Potter fans. Not only does Lithgow play a character similar in age and demeanor to Dumbledore, but the star of the film is also none other than Voldemort actor Ralph Fiennes.

1 Nick Frost In Sick Note

Sick Note Rupert Grint & Nick Frost

Nick Frost is arguably one of the most well-known confirmed cast members for the new Harry Potter series, and while fans may have already watched his more famous films, such as Hot Fuzz, they might not yet know they can watch him alongside the former Ron Weasley actor, Rupert Grint.

Sick Note is a comedy series where Nick Frost and Rupert Grint's characters form an unlikely and completely incapable duo, navigating a fake cancer diagnosis. After the announcement that Nick Frost will be playing Hagrid, it feels particularly funny to watch him interact with an actor who will always be synonymous with Ron Weasley.
