This article from The Daily Mail also features some lovely quotes from director, Ian Rickson, about Rupert:
Rickson explained how he met Grint and then placed him in the Mojo read-through.
‘I’d seen the Potter films with my daughter and always thought Rupert was truthful as Ron Weasley.
There’s something ordinary and centred about him, and in this world of Mojo you want that grittiness,’ Rickson told me.
He noted that he’d spoken to David Yates, director of the final four Potter pictures. Rickson recalled that Yates had told him Grint had ‘hidden depths’ as a thespian.
This will be a completely new role for Rupert and a huge step for him as an actor. We fully support him and have all the faith in the world that he will be absolutely brilliant on stage.
Rupert will have some amazing costars on stage, including Ben Whishaw, Brendan Coyle and Daniel Mays.
The above-mentioned article also describes Rupert‘s character Sweets:
Grint will play a minor hood called Sweets who pops amphetamines like Smarties and does a sort of double act, full of comic menace
Let us know in the comments if you’re planning to go see Rupert on stage in Mojo and how excited you are for him to be doing this play.
