'Wild Mountain Thyme' trailer triggers Irish accent outrage in Ireland with Emily Blunt, Jamie Dornan

"Wild Mountain Thyme" has set off Irish accent alarms in Ireland, after the rom-com's first trailer was revealed Wednesday, featuring cast members Emily Blunt, Jamie Dornan and Christopher Walken – yes, Christopher Walken – attempting the challenging accent.

Oscar-winner John Patrick Shanley's film (opening Dec. 11), based on his 2014 Broadway play "Outside Mullingar," takes place in Ireland's County Mayo and centers on whether Blunt's besotted Rosemary Muldoon will get together with Dornan's Anthony Reilly.

Walken portrays Anthony's father, who is trying to sell the quaint family farm to an American nephew played by Jon Hamm, who had no need to attempt the accent.

The Irish reaction to the trailer has brought back memories of Tom Cruise and then-wife Nicole Kidman portraying Irish immigrants in the 1992 drama "Far and Away."

RTE, Ireland's national radio and TV broadcaster, trumpeted an article with the headline, "Irish accent emergency declared after 'Wild Mountain Thyme' trailer.'"

The official account for the Dublin Airport tweeted the trailer Nov. 10. "There’s fashion police, grammar police. We even have airport police. Is there such a thing as accent police? If so, somebody better call ‘em," the cheeky tweet stated. "On the upside, Ireland looks nice."

The National Leprechaun Museum of Ireland, not often noted for its film commentary, felt compelled to weigh in on the trailer. "Even we think this is a bit much #WildMountainThyme," the museum's tweet said.

Britain's BBC investigated and handled the outcry more critically, asking, "'Wild Mountain Thyme': Is an Irish accent the hardest to master?"

"Fifty Shades" star Dornan, who hails from Northern Ireland, has faced the most criticism.

"The saddest part about the 'Wild Mountain Thyme' trailer is that Jamie Dornan is an actual Irish person," wrote one Twitter user.

"We were both terrified, I was like, no, we're going to be good," Dornan told People.com when introducing the trailer. "Yeah. Admittedly, a lot easier for me ... I'm actually from about 120 miles from where the movie is set, and Emily, there's an ocean between her and where the movie is set. Or the Irish Sea, certainly."

Blunt said in the same interview that Dornan assured her "that I sounded Irish and I'm going to believe him. So if he's wrong, I'm going to blame him for any backlash on my accent."

That backlash did materialize. "I am only managing about ten seconds of the Wild Mountain Thyme trailer per attempt and my thoughts and prayers are with all actual Irish people at this difficult time," wrote one Twitter user.

Brendan Shanley, an Irish cousin to director, leapt to to the defense of "Wild Mountain Thyme" in an interview with the Britain's The Times.

"Donald Trump didn’t get as good a coverage," Shanley said. "How can you make a judgment on someone’s tone in a trailer? It’s taken out of context. On a film trailer, you will get different accents because that’s the mood of (a particular) line. But if you listen for the entire film it will settle, and be different. It was the same in the play."

The Irish Embassy in Washington posted the most politically minded response to the furor.

"To be fair, Irish accents are hard (we struggle with them at times)," the tweet said. "But otherwise #WildMountainThyme looks great. And, in Jamie Dornan & Emily Blunt, presents a remarkably realistic depiction, visually at least, of the average Irish man & woman. Truly, we are a beautiful people."
