The Golden Globe-winning actor, who plays multi-millionaire antagonist Logan Roy on the hit HBO show, said his socialism is rooted in his experience of poverty as a child.
His father died when he was eight years old, and his mother was placed in an institution after suffering from severe mental illness.
“When you know poverty you know what socialism is and that we have to look after our people,” Cox said.
The 73-year-old also admitted that he is a “bit of a hoarder” when it comes to clothes, and chose a sewing kit as his luxury item for the island.
“It is one of those things you are left with, an insecurity. It has to come out somewhere.”
Cox chose tracks by The Beatles, Jacques Brel, Joni Mitchell and Johnny Cash – find the full interview here.
