Irish American actor John C. Reilly, who stars in the new film Kong:Skull Island, has revealed he’s applying for Irish citizenship.

The Chicago-born actor, who spent time in Kerry filming The Lobster, told RTÉ that he hoped to return to Ireland “as soon as possible.”

"I'm trying to get citizenship there right now," he said. “I hope someone has the good sense to send me a passport."

Reilly, whose father is of Irish descent, has previously spoken about his Irish roots. In 2013, the actor told The Late Late Show that he had a "very Irish upbringing, I think I had 35 first cousins", adding they had a reputation for being "insane.”

In Jordan Vogt-Roberts' new Kong: Skull Island, which also stars Tom Hiddleston, Brie Larson and Samuel L. Jackson, Reilly plays a World War II veteran who has been stranded on the titular island for 28 years.

"Yeah it was a lot of fun to play, I love that World War II era, the clothes and the music, the slang of the time, and I like the way men were kinda "can-do" men back then," said the actor.

The film was shot in various locations across Australia, Hawaii, and parts of Vietnam that had never been captured on film before.”

“The people in Vietnam were so happy we were there, it was really a lot of fun,” said Reilly.

Comparing Vietnam to Kerry, he said, laughing: "Not a big difference ironically.”

“No of course [there are differences]. Both very green places, a lot of water, lot of islands and little rocky outcroppings, but pub life's a little better in Kerry, I'll say that and it was a little easier for me to get around in Kerry because I speak the language, or at least one of the languages.

"It's tough to compare the two but I had a good time in both places."
