Martin Sheen thinks working with family is great - shame it doesn't pay well.
The West Wing star, who was directed by his son Emilio Estevez on his latest film The Way, joked that collaborating with relatives was "very cheap".
"You don't make any money when you're working with family, but you get to play great parts and see great things," he said.
In the film Martin plays Tom, an American doctor who scatters the remains of his dead son along the 500-mile Camino de Santiago walk from the French Pyrenees to Santiago de Compostela in the north west of Spain.
Speaking at The Way's London premiere, Emilio - who also scripted the movie - revealed it was his dad who provided the inspiration for the father-son tale.
"He'd done part of the Camino with my son - who not only came home and talked about it as well, but decided to move back and met a girl on the Camino. He married her and he's been living in Spain for eight years and so he's been another source of inspiration for me. On Martin's urging, we said let's go to Spain and make a film," he added.
"In this instance the son's no longer with us and it's the father getting closer to the son in death than he ever did in life and discovering what the son was all about."
:: The Way is released in UK cinemas on April 15.
