He might be a Hollywood superstar, thanks to his role in Marvel blockbuster Ant-Man, but Paul Rudd says he'll be "p***ed" if he never appears in comedy series Moone Boy again.
The TV show follows the antics of schoolboy Martin Moone and his imaginary friend Sean Murphy - played by Chris O'Dowd.
Paul (46) was one of the special guests in the final episode of the third season playing the part of Grandad Moone's piano-playing imaginary pal.
"It was great because not only is it a great show, and I got to play an awesome imaginary friend," he said.
"But because I got to go to Ireland and Ireland's my favourite place on earth. No bull.
"So I don't care what happens or whatever I'm working on, if Chris writes more Moone Boy - and I know that's a big 'if' because apparently he's done - I'm there.
"At least, I better be there or I'm going to be p***ed," he added,
While it's unlikely we'll see Moone Boy on the small screen again, Rudd could nab a part in the upcoming movie.
O'Dowd, who created the show with Nick Vincent Murphy recently revealed they were working on adapting the show for the silver screen.
"We're working on a special or a film," Chris said.
"I felt it needed a little break because I thought we had written all the stories for an 11-year-old that we could conjure up.
"So we thought it would be fun to revisit when he's 14, 15 and dealing with girls, so we'll have more opportunities to go into different kinds of plots," he added.
Meanwhile, Clueless star Rudd is a big fan of Ireland. Last year, he visited Donegal with Game of Thrones star Peter Dinklage and Walking Dead star Dallas Roberts for one of his friend's stag.
"First of all, Ireland is the best place on Earth. It is hands down the greatest country, it's the best place," he told American chat show host David Letterman after his trip.
