The Harry Potter HBO series cast just got bigger. Harry Gilby, Jasper Talbot and Hannah Chinn have joined as Charlie Weasley, James Potter and Lily Potter, Variety reports. It is a fan story, but also a production story: the show is shooting Season 2 while Season 1 is still weeks from release. Here is what’s new and what crews can learn about call sheets.
Harry Potter HBO Series Cast: Who Just Joined
- Harry Gilby as Charlie Weasley, the character’s first screen appearance, since he was not in the films.
- Jasper Talbot as James Potter and Hannah Chinn as Lily Potter, Harry’s parents.
- All three appear in Season 1, titled “Harry Potter and the Philosopher’s Stone”.
They join Dominic McLaughlin as Harry, Arabella Stanton as Hermione and Alastair Stout as Ron, with John Lithgow as Dumbledore, Janet McTeer as McGonagall, Paapa Essiedu as Snape and Nick Frost as Hagrid. Variety’s cast list now runs to more than 30 named actors.

Release Date and Season 2 Filming
According to Variety, Season 1 premieres on HBO on December 25. Season 2, based on “Harry Potter and the Chamber of Secrets”, is already filming at Leavesden Studios outside London. Kit Harington joins Season 2 as Gilderoy Lockhart, with Lenny Rush as Dobby, Billy Barratt as Tom Riddle and Rafe Spall as Arthur Weasley.

Francesca Gardiner writes and executive produces, and Mark Mylod directs multiple episodes. Running two seasons in parallel means the production juggles new casting, ongoing shooting and release prep at the same time, which is exactly where clear daily paperwork pays off.
Call Sheet Lessons for Big Ensemble Shows
A show this size runs on paperwork. Whether you’re shooting a fantasy series or a ten-person web show, these habits keep a large cast moving.

1. One source of truth per day
When one season is in post while the next is shooting, old schedules pile up fast. Publish one current call sheet per day and replace earlier versions.
2. Plan around young performers
Many lead roles here are played by children and teens. Most places strictly limit working hours for minors, so call times, tutoring and chaperones belong on the call sheet, not in someone’s notes.
3. Stagger cast calls
Large group scenes in hair, makeup and costume can swallow a morning. Stagger calls by department so principals are not waiting in trailers.
4. Flag creature and VFX scenes
Characters like Dobby mean extra crew, reference passes and special kit. Note them on the sheet so departments arrive ready, and list any stand-ins or reference doubles alongside the main cast.
