Belfast Accent - Can You Still Do It?

i'm finally going to go and see the film belfast. I've been wanting to see it for quie a while, and mamen is not the only person who's recommended it to me. Are the very famous people starring inthi, yes, i can't remember exactly right now. Who? Judy dench, i think, dame judy dence, and a few other people. And i'm very curious, as a local unlugarino, to see how they do the accent because belfast accent is a very particular one. The tradition in the theatrical world is to associate a particular accent with shakespeare.
