Liam added: “After lunch, I told George Lucas I brought my son and he had to get down and go over to R2-D2 and just hug him.
“And he wasn’t surprised and had a smile on his face. He said, ‘Yeah he has that effect on children.’
“I said, ‘But my kid is two years of age. You know, it’s a big chunk of metal.’ But he just knew it was cuddly and comfortable and friendly.”
Micheál, however, revealed not all his Star Wars memories were so positive.
He said: “It was kind of traumatising at the age of five seeing my dad sliced in half by a lightsaber or blown up in some crazy factory explosion, and also kissing somebody else.”
He is, of course, referring to Qui-Gon’s death at the hands of Darth Maul.
