Two Tourists at Santiago De Compostela

Martin Sheen and Emilio Estevez were amongst the pilgrims at the Papal Mass this weekend at the Cathedral of Santiago De Compostela in Spain

They were in Spain working on their latest movie "The Way", which is about the ancient pilgrimage of the Camino de Santiago in Spain.

Sheen `s father was originally from this region of Spain but emigrated to America.

In 'The Way,' Sheen plays a California doctor who struggles with the fact that his son has thrown in his studies to go off to travel the world. But after his son dies in a storm in the Pyrenees, Sheen flies to France and once there, decides to do the pilgrimage in his son's honour, scattering his ashes along the way.

In the interview with Channel 4, Sheen talks about the recent child abuse scandals

He said:

"If the Vatican ran out of dough and had to close up shop tomorrow, I'd still be a Catholic. Because I love the faith ...

The institution has a presence in the world but it's human and it's flawed and it's all-male, so it's bound to make some mistakes.

But the faith is something different. The faith is what the whole Church is about."
