WATCH: Sienna Miller Absolutely Butcher The Irish Accent

We've heard our fair share of actors' shite Irish accents on screen in recent years. 

But this? This could very well top the charts as the WORST impression of an Irish accent EVER. 

The move in question is Live By Night starring Sienna Miller, Ben Affleck, Elle Fanning, Chris Messina, Zoe Saldana, Chris Cooper and our very own Brendan Gleeson. 

Affleck also produced the movie alongside Leonardo DiCaprio. 

But lads, that accent?! C'mon Sienna, that's just insulting.
