When "Harry Potter and the Sorcerer's Stone" premiered on screen in 2001, its three young stars instantly became household names. But some fans wondered how Daniel Radcliffe, Rupert Grint, Emma Watson and their Hogwarts classmates would fare after the "Harry Potter" franchise wrapped in 2011. Would their careers thrive after the success of the movies? Or would playing such well-known characters for a decade lead them into typecasting abyss?
And seriously, what would they look like as adults?
Ahead of the 20th anniversary of the very first "Harry Potter" book's release, and because we're feeling extra nostalgic, HuffPost decided to do a little digging in order to find out what those wizarding world kiddos are up to today.
Daniel Radcliffe (Harry Potter)
Radcliffe has been keeping busy since he starred as The Boy Who Lived. He played beat poet Allen Ginsberg in 2013's independent film "Kill Your Darlings" and had a cameo in 2015's "Trainwreck." In 2016, he played a corpse in the dark comedy "Swiss Army Man," giving us this awesome GIF:
The actor has also signed on to star in an apartheid prison-break film called "Escape From Pretoria" and will play a low-ranking angel in "Miracle Workers," a "heaven-set workplace comedy" produced by Lorne Michaels.
Radcliffe has done quite a bit of theater since he left the franchise, too. In 2011 he appeared in "How to Succeed in Business Without Really Trying" on Broadway and starred in "The Cripple of Inishmaan" in 2014. He is currently starring in "Rosencrantz and Guildenstern Are Dead" on London's West End.
Oh, and he's grown a beard for his upcoming film "Jungle." If that doesn't say "all grown up," we don't know what does.
Rupert Grint (Ron Weasley)
Grint is currently starring in two shows. He plays a character named Charlie in Crackle's "Snatch," based on Guy Ritchie's 2000 film of the same name, and he stars in the comedy "Sick Note" alongside Don Johnson, which will air this year on the U.K. station Sky Atlantic.
And although Grint is now all grown up ...
... He's a big fan of posting awkward throwback photos on Instagram showing him with his "Harry Potter" co-stars.
Emma Watson (Hermione Granger)
Aside from her work in women's rights ― she currently serves as a United Nations Women goodwill ambassador ― Watson is pretty much all-around slaying. (We've also learned she's a diehard Tina Turner fan.)
Right now, the actress can be seen starring alongside Tom Hanks in "The Circle." In March, she helped smash box office records as Belle in the highly successful live-action "Beauty and the Beast" movie.
She probably deserves some awards simply for keeping a straight face while acting alongside this ridiculous pre-CGI Beast:
Tom Felton (Draco Malfoy)
Tom Felton has been getting plenty of acting work since his stint as a Slytherin.
He showed up in 2011's "Rise of the Planet of the Apes" and currently plays Julian Albert on The CW's "The Flash." He has also signed on to star alongside Daisy Ridley and Clive Owen in the romantic tragedy "Ophelia," which is currently filming.
Evanna Lynch (Luna Lovegood)
Since the final "Harry Potter" movie wrapped, Evanna Lynch has busied herself with Potter-related projects, reprising her role as Luna Lovegood in Harry Potter TV movies and video games. She also landed a gig in the 2013 movie "G.B.F.," distancing herself from her role as the quirkiest Ravenclaw at Hogwarts.
Other than that, she's been posting cute photos of her cat Puff ...
... And freaking out over getting a salmon patronus on Pottermore.
Matthew Lewis (Neville Longbottom)
Matthew Lewis, who played the adorably awkward Neville Longbottom, surprised everyone when he grew up to be a full-on heartthrob.
Career-wise, he appeared in 2016's "Me Before You."
Oh, and he's also an amateur T-shirt designer, apparently.
Bonnie Wright (Ginny Weasley)
Bonnie Wright has tried a bunch of things since she left the wizarding world, including modeling, writing and producing.
Her latest gig, however, is directing. Her most recent project, "Phone Calls," is a web series that explores how people communicate when we're not face-to-face. She premiered the project at the Tribeca Film Festival in April, where she also bumped into her old co-star Watson.
Other than that, it seems like the girl who once played Harry Potter's love interest still enjoys a cold butterbeer from time to time.
Robert Pattinson (Cedric Diggory)
Robert Pattinson, who played the charming Hufflepuff Cedric Diggory, has fared pretty well since he left one magical franchise for another. Pattinson became a household name when he starred in the "Twilight" franchise and began dating his co-star Kristen Stewart. After their split, the actor stepped out of the spotlight and began concentrating on smaller films like 2016's "The Lost City of Z."
His latest film, "Good Time," was screened at the Cannes Film Festival, where it received positive feedback.
Scarlett Byrne (Pansy Parkinson)
Scarlett Byrne has kept herself busy since she tried to hand Harry Potter over to Lord Voldemort. She played Nora Hildegard in "The Vampire Diaries" and, earlier this year, she posed nude for "Playboy."
"I'm very proud," she said in an Instagram post.
Luke Youngblood (Lee Jordan)
The actor who played the enthusiastic Gryffindor who kept the crowd up to speed during school Quidditch matches has done pretty well for himself.
Luke Youngblood had a role on "Community" as Magnitude ― the guy with the catchphrase "Pop! Pop!"
He also starred on ABC's "Galavant," and is pretty easy on the eyes.
Freddie Stroma (Cormac McLaggen)
Cormac McLaggen wasn't very enticing with his creepy advances toward Hermione. But Freddie Stroma, the actor who played the sleazy Gryffindor, has all kinds of appeal.
Stroma starred in the first season of "The Bachelor" spoof "UnREAL," and had a small role in Season 6 of "Game of Thrones." He also showed up in the ABC drama "Time After Time."
Alfred Enoch (Dean Thomas)
Little Dean Thomas is all grown up. Alfred Enoch, who portrayed the Dumbledore's Army member, had a leading role in "How to Get Away with Murder."
His character was killed off last season, but Enoch isn't done with the small screen quite yet. He'll be appearing on the forthcoming Netflix series "Troy: Fall Of A City."
James and Oliver Phelps (Fred and George Weasley)
One of the first things James and Oliver Phelps did after "Harry Potter" wrapped was stop dying their hair (and eyebrows) red. The brown-haired brothers still act, and while they occasionally take on projects individually, they're both appearing in the upcoming film "Our Worst Enemy" and recently teased a project called "Twin Cities" on Instagram.
Other than that, Oliver, who played George Weasley, allegedly has quite the collector item. The actor reportedly displays his character's ear ― the one that was zapped off during a battle ― in his home. How ear-ie.
Devon Murray (Seamus Finnigan)
Devon Murray hasn't done much screen work since his "Harry Potter" days. In late 2016, he opened up about his struggle with depression and suicidal thoughts on Mental Health Day.
Murray got some online support from fellow actress Shannon Purser, who played Barb on "Stranger Things."
The actor also heard from fans who said they deal with similar issues.
Here's wishing him the very best.
Jessie Cave (Lavender Brown)
Jessie Cave, who played the girl who caused Hermione heartache by dating Ron, has had parts in shows like "Call the Midwife" and "Trollied." But she considers herself more of a creator than an actor nowadays.
In 2015, she published a book of cartoons called "Love Sick" and, on her website, sells many of the drawings she posts on her Instagram page.
Katie Leung (Cho Chang)
Katie Leung, the Scottish actress who played Harry Potter's first crush, has done some television and theater work since her Hogwarts days. Most recently she starred in "Snow in Midsummer," a modern retelling of a 13th-century Chinese classic at the Royal Shakespeare Company.
