Boyzone frontman to provide the singing voice of Postman Pat in upcoming film.

Ronan Keating has joined the cast of the upcoming Postman Pat: The Movie.

Keating will provide the singing voice of Postman Pat in the big screen outing produced by RGH Entertainment’s Robert Anich with Rubicon’s Randa Ayoubi and David Corbett.

Dreamworks Classics’ Eric Ellenbogen and Doug Schwalbe serve as executive producers.

Currently in production, the film is directed by Mike Disa from a screenplay co-written by the award-winning Kim Fuller, Annika Bluhm and Nicole Dubuc. The cast is led by Stephen Mangan as Postman Pat, with Jim Broadbent, Rupert Grint and David Tennant also set to star.

Keating, who will also have a cameo appearance in the film, commented: “It’s been a true honour to help bring Postman Pat’s singing voice to life. I grew up watching Pat and all the great characters in Greendale so I can’t wait to take my kids along to see them all on the big screen.”

Postman Pat: The Movie will be released in 3D in cinemas across the UK on May 23, 2014.
