It's been a long time since Roddy Doyle has written for the big screen, but he is back with a new film, Rosie, which deals with the topic of homelessness.

Rosie tells the story of a day in the life of a woman and her family as they try to find somewhere to live. It was inspired by a radio interview Roddy heard in which a woman described being in a similar situation.

Roddy says our image of homeless people is often stereotypical: "There is the notion that they deserve it or that they've done something wrong. We don't see the families very often."

He thinks that our own attitudes to social housing are partly to blame for the current homelessness crisis.

"We've decided that we can't interfere with the market, and that allowing working class people to live in close proximity to each other is fundamentally a bad idea."

Roddy's main ambition with this film was "to put human faces on statistics."

According to Focus, 180 families have gone through the same experience in the first eight months of this year. Although a significant figure, Roddy says it's not astronomical, and therefore we should be able to do something about it.
