Penn to mark two milestones here - turning 50 and divorce from Robin

HOLLYWOOD legend Sean Penn is marking two milestones in Dublin -- his divorce to wife Robin and his 50th birthday.

The Herald can reveal how the Oscar winner has spent the past few days in an exclusive Dublin 2 hotel as he gears up to begin filming on new flick This Must Be The Place.

It was confirmed this week that he is now officially divorced from actress Robin Wright, with a judgement ending their 14-year marriage at the end of last month.

The pair had been involved in an on/off relationship, with Wright filing for divorce last August, the third time the couple petitioned to either separate or divorce.

They will share custody of their 16-year-old son Hopper, and they also have a 19-year-old daughter, Dylan.

Meanwhile, double Oscar-winner Penn will also celebrate his milestone 50th birthday in Dublin on August 17.

And a source has said he is lapping up Irish culture after booking into a top hotel on the southside which is close to all the major attractions.

"He's here to work and takes every project very seriously, but he's also hoping to have a bit of free time to go to some museums or art galleries while he's here and get a real taste of culture," said an insider.

"He's also looking to mark his 50th birthday in a unique way while he's here in Ireland."

Filming on his new movie will start on August 16. Co-stars include fellow Academy Award-winner Frances McDormand.

A project which will significantly boost the Irish movie industry, the English-language movie is being made by Italian director Paolo Sorrentino.

The crew are expected to spend the next month filming in various locations around Dublin and Wicklow.

Penn, who's one of the few actors to receive two Academy Awards, plays an aging rock star who pursues the Nazi criminal who took his father's life in a concentration camp.

His character is called Cheyenne, who lives a quiet life in Dublin with his wife, played by McDormand.

When his father, a holocaust survivor, passes away in New York, he embarks on a journey to track down his father's nemesis.

The movie caused a huge stir in the director's native home of Italy after it was revealed that, for the first time ever, an Italian bank was partly funding it.
