Daniel Radcliffe wants to play Batman's sidekick Robin.

The 'Harry Potter' star believes he would be the ''perfect'' choice to take on the role of the superhero sidekick in the rumoured upcoming 'Batman' reboot starring Ben Affleck.

When asked which movie franchise he would consider starring in, he told Buzzfeed: ''Batman. If they reboot that again, I'll do that, too.

''It's happening isn't it? With Ben Affleck. I could be Robin. I'm perfect.''

Affleck, 41 - who is to make his debut as the Caped Crusader in 'Batman v. Superman: Dawn of Justice' next year - will reprise the role in 'The Justice League' in 2017 and it's now been reported that he's landed his own solo outing, set for 2019.

According to Latino Review, the film is speculatively called 'The Batman' and is being planned for four years' time because of Affleck's busy schedule.

Meanwhile, Radcliffe, 24, is also said to be interested in joining the legendary 'James Bond' franchise as an ''evil mastermind''.

A source said previously: ''Daniel thinks he would be an excellent villain in the Bond films. He loves the franchise but admires the villains as much as Bond.

''He feels he could appear as a modern bad guy, an evil mastermind who wants to take down MI5.''
