HOLLYWOOD came to town as heartthrob Josh Hartnett filmed scenes for his upcoming TV series in a Dublin park.
Dog walkers and joggers in Cabinteely Park did a double take as they found a section of the grounds cordoned off and transformed into a Wild West show and travelling circus.
And leaning broodily by a tree was none other than Josh Hartnett, star of 'Black Hawk Down' and 'Pearl Harbour'.
It was the first day of filming on 'Penny Dreadful', a new eight-part US television series from Oscar-winning director Sam Mendes and writer John Logan, who last joined forces on the James Bond hit film 'Skyfall'.
The series, which will be filmed at a number of locations around Dublin as well as at Ardmore Studios in Co Wicklow, tells the 'origin' stories of a number of leading figures from gothic horror literature, including Dr Frankenstein, Dracula and Dorian Gray and is set in Victorian London.
Producers recently held an open casting for extras at the Gresham Hotel.
Yesterday around 60 of them were on set – along with a number of coaches and horses.
The series is expected to be broadcast early next year on US cable network Showtime.
Meanwhile, actor Dean Norris, from the hit US TV Show 'Breaking Bad' also arrived in Dublin last night.
Norris played long-suffering Drug Enforcement Administration (DEA) agent Hank Schrader, whose chemistry-teacher brother-in-law Walt turns out to be expert crystal meth cook and international drugs lord 'Heisenberg'.
The show wrapped up a five-season run in the US, and on Netflix in Ireland, this week.
Norris, who has featured in more than 100 films and TV shows including 'Total Recall', 'Starship Troopers' and 'The West Wing', will be on RTE's 'Saturday Night Show' with Brendan O'Connor tonight to chat about 'Breaking Bad's explosive last season.
He arrived at Dublin Airport yesterday afternoon, and appropriately enough for his home-brew enthusiast character – who makes 'Schraderbrau' beer in his garage – he took the Guinness Storehouse tour shortly after landing.
He referenced Hank's obsession with collecting mineral rocks, when he tweeted last week: "Going to the Emerald Isle! A country's poetic name is a mineral! Oh I'm in love already."
Announcing his trip, he tweeted: "Stock up on the Guinness and whiskey, gonna be doing some Irish-style partying."
