Keating is among the all-star cast topped by comic actor Stephen Mangan who have clubbed together to bring children’s favourite postie to the big screen.
Our trusty postman, Pat Clifton, may have been doing the rounds with his black and white cat Jess since September 1981, yet in those 33 years, doesn't appear to have aged a day.
Pat is at the heart of village life in the cosy community of Greendale, where he lives in Forge Cottage with his wife Sara (Susan Duerden) and football-mad son Julian (Sandra Teles).
Sara has always dreamt of going to Italy, so when Pat discovers a trip for two is the top prize in the TV reality show You're The One hosted by Simon Cowbell (Robin Atkin Downes), he prepares to belt out a ballad.
"Think of it as singing in the shower," Julian tells his father soothingly, "but in front of lots of people... and with your clothes on."
Against the odds, Pat's audition charms the usually stony-faced Cowbell.
Within days, Pat has become a nationwide celebrity and he gets caught up in the media hoopla, which takes him far away from his loved ones and his job at the Special Delivery Service (SDS).
In Pat's absence, SDS efficiency expert Edwin Carbunkle (Peter Woodward) plots to replace all of the human staff with robot doppelgangers.
Meanwhile, the grand final of You're The One beckons and Pat prepares to compete against teenage singer Josh (Rupert Grint) and his pushy father (David Tennant).
