Grint Cast In 3D “Postman Pat” Film

“Harry Potter” star Rupert Grint will join Jim Broadbent, David Tennant and Stephen Mangan as part of the voice cast for a 3D film adaptation of British kids series “Postman Pat” says The Hollywood Reporter.

Classic Media and Rubicon Group Holding are developing “Postman Pat: The Movie — You Know You’re the One” to celebrate the character’s 30th anniversary, timing the release for Spring 2013. Production kicks off this month.

The story has Pat coming face-to-face with the temptations of money, status and a shiny new suit when he enters a national TV talent show competition that threatens to tear him away from his hometown of Greendale and the friends he loves.

Mike Disa helms from a script by Kim Full and Annika Bluhm, the producer of the TV series version. Icon Film Distribution will distribute in the UK and Ireland.
