Harry Potter

The 33-year-old actor has welcomed his first child with partner Erin Darke, whom he met while filming Kill Your Darlings in 2013.

While the show hopes to honour Ms Rowling's source material, she will "not run the show day to day or serve as its primary creator", it is reported.

Harry, Ron and Hermione could return to screens in a seven-season TV show, according to reports.
