While we all know us Irish like to play it cool around the Hollywood A-Listers, it's still nice to know when they are stopping by. And Josh Hartnett is doing much more than stopping by, he will be pretty much taking up residence here over the coming months as filming of Sky Atlantic's Penny Dreadful begins.

The star spent a great deal of time here last year too, when the first series of this eery Victorian drama was filmed. We even got to talk to him about his time here a while back, when he told entertainment.ie about all his favourite Dublin hotspots to hit up of an evening.

He's not the only bigwig to be wandering the streets of our capital too, as Timothy Dalton and Eva Green also star in the drama, which is all filmed in locations around Dublin and beyond. In fact, the whole first season of the show brought a whopping €33 million to the Irish economy in terms of spend on local jobs and services. Eh, who needs Garth Brooks when we've got Penny Dreadful? And we're pretty sure Josh Hartnett would rock a stetson.

Joining the cast this year is also Cork's own Sarah Greene, who you may have seen on The Late Late Show last Friday alongside Deirdre O'Kane promoting their film 'Noble'. She will play Hecate in the series, the powerful daughter of Evelyn Poole played by the returning award-winning Helen McCrory (Harry Potter and the Deathly Hallows).

In case you missed the first series of this terrifying psychological thriller, it is written and executive produced by three-time Oscar nominee John Logan (Hugo, The Aviator, Gladiator) and executive produced by Oscar winner Sam Mendes (American Beauty, Skyfall). It features some of literature's most iconic characters from Frankenstein to Dorian Gray, who all seem to be trapped in some kind of 'half world'.

Production will begin this Friday, so if you see any Victorian or Gothic looking sets around Dublin, you'll know what it's about. Better yet, if you see any of the stars themselves, do let us know. Not that we'll be wrecking their heads or anything, but you know, Irish hospitality is very important to us.

Let's just hope there are no awkward selfies with Josh on The Late Late Show this time round, we're better than that people.
