Hollywood star Emily Blunt lived in fear of an Italian stalker when she began filming Wild Mountain Thyme in Co Mayo last year.
Before Blunt arrived in Ireland, gardaí in Ballina were briefed by film producers about the fixated fan, amid fears he would travel to Ireland.
A security source confirmed gardaí issued a nationwide alert to all ports and airports regarding the Italian national following an assessment.
He is known to have attempted to contact Ms Blunt many times and has, in the past, travelled to where she is filming.
The notice included a picture and background information on the man, who a source described as “fixated” with the actress.
The notice ensured that if the man entered Ireland, gardaí would be notified.
However, he never attempted to travel, and Blunt reported feeling very happy and safe with her family during filming, where they stayed at a lodge at the Mount Falcon Estate.
A security source said gardaí were consulted by film production management before the actress arrived in Ireland.
“Gardaí made sure every measure was put in place to ensure she and her family were safe,” said the source.
“Staff members of the hotel were also made aware of the situation in case he tried to check into the hotel or tried to gain access to the grounds.
“In terms of security and safety, it (Mount Falcon) was an ideal place really, because while it’s within a couple of minutes from the town (Ballina), it has a long avenue and very open grounds.
“Every person who walks or drives in there will be seen,” they added.
Gardaí checked with Ms Blunt and the film producers regularly during her stay, and she reported feeling safe and happy.
A source said gardaí were powerless to stop the man travelling to Ireland.
“There is very little that can be done in terms of stopping someone arriving on a flight.
“Which must be very frustrating for people in her (Ms Blunt’s) position.
“He could certainly be questioned as to why he was here, but beyond that, if no crime has been committed, he can’t be detained or sent back,” they explained.
Ms Blunt arrived in Mayo in September 2019 and stayed for 12 weeks.
Initially, due to fears for her safety, Ms Blunt rarely ventured outside the sprawling grounds of the Mount Falcon Estate.
However, after a few weeks, she began to socialise in Ballina and was pictured a number of times out and about.
The actress was generous with her time and was described as “very kind” by locals who met her during her stay.
During a break in filming, Ms Blunt paid a visit to the Kilmoremoy Kids Drama Group’s rehearsal.
The Western People reported that the youth group was in the middle of running through their final scenes for their play Into the Wood, when Ms Blunt walked in the door, leaving the children amazed.
“She was very good and very kind. She was talking to all the kids and took photos with them all, and asked to see another scene from the show,” said Jack Cronin, the group’s director.
“She spent about half an hour with us altogether,” he added.
The Irish embassy in the US has joked that Emily Blunt and Jamie Dornan present “a remarkably realistic depiction” of Irish people in the trailer for their new film Wild Mountain Thyme, adding: “We are a beautiful people.”
