Irish accents have proven extremely difficult for actors to adapt.

In the past, we've even covered the worst Irish accents in movie history.

A few more might have to added to the list following the release of 'Wild Mountain Thyme'.

There was an uproar when the trailer dropped, and people were baffled how even Northern Irish actor Jamie Dornan's accent was all over the place.

At least they're not making out that Irish accents are easy to do, as Dornan's co-star Emily Blunt acknowledges.

In an interview with THR, the actress was asked about the difference between Irish and English accents, and whether the notion that the Irish accent is hard to nail down is true.

"Oh God, it’s completely different," she answered. "But also, if you think about England, there’s 100 accents or more. I don’t know how many accents there are just in England, and it’s the same in Ireland. I think there’s 50 to 100 different accents just in Ireland.

"Even in Dublin, there’s North and South Dublin, and they sound completely different. So we had to learn a very specific midland, rural, quite thick accent, and it sounds completely different from a metropolitan, sort of Dublin Irish accent. I don’t even know all the accents.

"So yes, and even for Jamie, who’s from Belfast, he has a completely different accent from how he spoke. So accents are tricky. You just do your best and that’s all you can hope for."

She's not the only one to struggle either.

'Pixie' cast members Olivia Cooke and Ben Hardy recently talked to us about how "daunting" they found attempting the accents.

'Wild Mountain Thyme' goes on demand on Friday, December 11th. 'Pixie' is showing in cinemas now.
