Every now and again, an actor goes to extraordinary lengths to create an unforgettable character and this is what Sean Penn does as he transforms into Cheyenne – a bored, wealthy, retired American glam rock star now living in Dublin. Based on The Cure’s Robert Smith, he is a complex character with the mannerisms and speech of a child who is afraid of the world around him. And he is a strange looking creature as he ambles around town in his the full eighties outfit that includes long teased hair and heavy makeup. His down-to-earth wife of 35 years Jane (Francis Mc Dormand) sees past the all this as does his best friend, sixteen year-old Goth Mary (Eve Hewson). When Cheyenne finds out that his father (who he hasn’t seen for thirty years) is dying, he returns to America and undertakes a road journey of discovery like you’ve never seen before.
