Radcliffe is on the shortlist for the coveted Best Actor in a Play prize for his turn in The Cripple of Inishmaan, but he faces fierce competition from fellow Hollywood actor James MCAvoy for his role in MACbeth, as well as Lenny Henry (Fences), Rory Kinnear (Othello) and Skyfall star Ben Whishaw (Peter and Alice).
Grint has followed his friend into theatre this year (13) and has landed a nod in the Newcomer of the Year category for his West End debut in Mojo. He faces rivals including Jack Huston (Strangers on a Train) and singer Tori Amos, who has been nominated for composing the score to her musical The Light Princess.
Other stars to have landed nods include Dame Helen Mirren, whose turn playing Queen Elizabeth Ii in The Audience scored her a nomination for Best Actress in a Play. She is going up against Captain America: The First Avenger star Hayley Atwell (The Pride), James MCAvoy's wife Anne-Marie Duff (Strange Interlude), Suranne Jones (Beautiful Thing), and Tanya Moodie (Fences).
The awards, which are voted for by theatre-goers, will be handed out at a ceremony in London on 23 February (14).
