Sean Penn has had confrontations with paparazzi in the past.

Sean Penn and Frances McDormand are set to film part of their movie,  ‘This Must be the Place,’ in Ireland next month.

The film is about an ageing rock star, who is trying to track down the Nazis responsible for killing his father.

The Irish Film Board is co-funding part of the production of the film, which is being co-produced by Element Pictures and is also funded by French and Italian backers.
