Harry Potter's Rupert Grint is set to star in Cherrybomb, a Belfast-set teen drama about two friends whose furious competition for a beautiful but manipulative girl has tragic consequences, according to Variety.

Kimberley Nixon (Angus, Thongs and Full-Frontal Snogging) stars as the girl, with emerging Irish actor Robert Sheehan playing best buddy and love rival to Grint's character.

Cherrybomb is the joint debut of co-directors Glen Leyburn and Lisa Barros D'Sa from a screenplay by Daragh Carville (Middletown).

No production date has been set.
