Death Eaters and wizards are finally laying down their swords, thanks to an unlikely common ground: the mail.

The "Harry Potter" movies may have come to an end, but fans of the franchise may be able to ease their heartache with the release of a new movie starring some of the series' most recognizable faces -- and voices.

The Guardian reports that Rupert Grint, David Tennant, and Jim Broadbent will have their very own post-Hogwarts reunion in the 3-D animated feature "Postman Pat: You Know You're the One."

The movie, scheduled for release in 2013, follows Postman Pat, the title character of a popular British children's show, on a journey from his mail route in the fictional village of Greendale to the city, where he shows off his skills in a talent competition.

Pat will be voiced by British actor Stephen Mangan, who currently stars as comedy writer Sean Lincoln in Showtime's "Episodes." Mangan says of his participation in the project, "I'm absolutely thrilled to be playing the world's best-known postman in his big-screen debut. However, when I excitedly told my 3-year-old son that I was going to be Postman Pat, he said: 'No you're not, dad, don't be silly.'"
