Return to Hogwarts premieres in the UK today, which will see the reunion of the Harry Potter stars for the 20th anniversary of the first film. 

Daniel Radcliffe, Emma Watson and Rupert Grint will all feature in the special, as well as Tom Felton and Helena Bonham Carter. 

Speaking on a clip of the reunion, Radcliffe, who played Harry Potter, said: "The thing that scared me the most was the implication that the most meaningful thing in our life was done.

"And there's something so joyous about seeing everyone and being like, 'It wasn't'."

Meanwhile Grint, who played Harry's best friend Ron said: "It's a strong bond that we'll always have.

"We're family. We'll always be part of each other's lives."
