Paul Rudd has said he loved working with "genius" Steve Coogan on new film My Idiot Brother.
The Knocked Up star revealed he was a huge fan of the British comedian who plays a self-righteous documentary maker in the film about an idealist, played by Paul, who barges into the lives of three sisters.
Paul said: "I think Steve Coogan is a genius and I've been a Steve Coogan fan for many years."
He went on: "Getting to work with him this summer on this film where I knew pretty much everyone I was working with, we were all kind of friends, and I didn't know Steve Coogan and when I heard he was going to be in it I was bouncing off the walls - he's incredible, really fun."
Paul, 41, was honoured by the US-Ireland Alliance in Los Angeles on Thursday at their pre-Oscars Oscar Wilde party.
The Role Models star joked he had a strong connection to Ireland, even though he was Jewish and born in America.
Paul said: "[I feel] very connected [to Ireland].
"I've been going there my whole life, well the second part.
"My father passed away, I spread his ashes there - he loved it as much as I did.
"I have an Irish pub in my house that I've built. My son's name is Jack Sullivan. This is pretty Irish stuff for somebody who is, by and large, really a Russian Jew."
