Micheál Richardson was just 13 years old when his mother died following a skiing accident in 2009 and now the aspiring actor has officially adopted Natasha's surname.

Natasha's mother Vanessa Redgrave told the Daily Mail: "He's taken, officially, the name of his mother. He's Micheál Richardson, not Micheál Neeson.

"That wasn't because he wanted to avoid his father's fame, which is enormous. He wanted to hold his mother close to him -- because she was a remarkable actress. Absolutely remarkable.

"Our quaint customs dictate we have to have a male name. I don't object. Why not? It's as good as any."

Meanwhile, Liam previously admitted he tried to talk Micheál out of acting as he wanted to shield him from rejection.

Liam said: "I tried to talk him out of it. The profession is all about rejection, you know? You go out for this part and you're rejected, and you're not rejected because of your education, you're rejected because of this. The space you occupy. You're too tall. You're too Irish. Your nose is too broken. You're too this, you're too that. So it's - you want to save your kids from all that, you know?"

Although the 'Taken' star wasn't keen on Micheál's career choice at first, the pair recently worked together on thriller movie 'Hard Powder', and Liam admits it was "nice" to act alongside his son.

He added: "We did a film called 'Hard Powder'. It's a thriller. It's got a dark comedic bend to it, as well. He plays my son, and he's, it was good to act with [him]! We had two or three little scenes together and it was nice."
