A Fleeting Meeting With Ronan Keating

I said in my original blog about Cannes to expect the unexpected at the film festival. Well, who would have thought that Ronan Keating would be here for a film and that torrential rain would dampen the spirits of everyone at the festival - including Ronan?

"I got here yesterday and it was pissing with the rain and I was like what the f***, Cannes? Come on. No, we weren't happy. I came from Sydney and you get off the plane after 25 hours and it's pissing with rain. Not happy."

He's not the only one. The festival is normally drenched with scorching sunshine and now it's just drenched.

The beautiful people now have their toned bodies covered with winter clothes and anoraks, the press who run around endlessly have blistered feet from damp shoes, and the stars who hit the red carpet have ended up looking like drowned rats by the time they've got up to the top of the famous steps.

Danish actor Mads Mikkelsen told me over a lunch for his new project Move On that the cast and crew of his film The Hunt by Thomas Vinterberg spent no more than two minutes on the carpet while the heavens poured. "I was so disappointed. We waited for our big moment and then it was like, is this it?!?"

The greyness has dampened the colourful glamour, the bleary eyes are no longer able to be covered up with sunglasses and the red carpet is now a rather disgusting squelchy shade of maroon.

Not good.

But the sun is finally creeping through the clouds as I meet up with Ronan, who's here for his acting debut in Goddess.

I have four minutes to talk to the ex-Boyzone frontman, but the You Say It Best When You Say Nothing At All singer is doing the opposite, as he charges through my questions passionately at about a thousand words per minute.

It's not surprising he's so passionate. He's been trying to get into cinema for the past 10 years.

"Honestly, I've been going to readings, auditions, and trying and it's been big stuff, like big directors and getting to the final five or six people and I've had representation in Los Angeles and the UK but I guess one thing as well is someone taking the risk. You know because it's not easy saying this guy could be an actor, this singer."

I'm reminded of the viral single I'm On a Boat, I'm On a Motherf**king Boat as he explained to me his first day on set.

"It was just the whole thing of being on a set, a film set, here I am I'm on a film set," and then he states the obvious in his excitement, "I have dialogue, I have lines, all the things happening at the same time, it was bloody incredible."

Believe it or not, Ronan is playing a marine scientist in Goddess, whose job is to save whales in the Antarctic.

But that's not what the film is about. It's about his on-screen wife who lives a lonely life sitting at home looking after her two kids. But all of a sudden she becomes an internet sensation by singing quirky numbers through her webcam.

I first met Ronan back in 1998 and he's always been incredibly serious. It seems now he's a changed man, and has started swearing now his role model days are behind him.

"I was shitting myself and my first day on set was with two kids in the scene with me. So my first day on set and I'm dealing with kids but it went bloody brilliant. It was frightening but it was great. I'll never forget that day."

Ronan announced his divorce from his wife Yvonne only last month after 14 years of marriage, but it seems like the Irish star is embracing his new lease of life.

"A lot has changed in my life in the last few years, big changes and this is the beginning of something very different. But I'm not going to walk away from music."

The movie doesn't have a release date in the UK as of yet, so we'll have to wait to see how good Ronan's acting chops are. So, I just had to ask him what he thinks of his film presence.

"By no means do I think I'm brilliant but I can act now where I couldn't do that before. I understand it, it's telling the truth, it's playing that character and being that character and not looking like you were acting. It was a long process to get there but I could walk into any role now, I'd be ready for anything. How I rate it, I couldn't tell you that."

And with that comment, the sun, like his burgeoning film career, miraculously blazed through the grey clouds.
