It's a good time to be Harry Potter superfan Jessica Williams.

Pottermore announced Friday that the Daily Show alum has been cast in an undisclosed role in Warner Bros.' untitled Fantastic Beasts sequel. "HELLO THERE," she tweeted after the news came out. "I AM SCREAMING BECAUSE I AM GOING TO BE IN FANTASTIC BEASTS." Screenwriter J.K. Rowling said she is "soooooo happy" for the actress, and after Williams thanked her three times, the author responded with an owl emoji, explaining, "There's no purple heron emoji, so."

Fans will also get to see Brontis Jodorowsky as alchemist Nicolas Flamel, a character first mentioned in Rowling's debut novel, Harry Potter and the Sorcerer's Stone. Addtionally, Derek Riddell has been cast as Torquil Travers and Poppy Corby-Tuech has been cast as Rosier; their characters' surnames belong to Death Eaters who served Voldemort in the Harry Potter series.

In April, Jude Law joined the ensemble as Albus Dumbledore.
