Son doesn’t know dad played ‘Harry Potter’

Daniel Radcliffe's son has no idea his dad was Harry Potter.

The 36-year-old actor has a young son, who turns three in April, with his partner Erin Darke. Radcliffe has revealed he's tried and failed to explain his job to the youngster.

During a conversation with Happy Sad Confused podcaster Josh Horowitz in New York, he explained: "Right now I'm just his dad and he has no idea what I do. Well he's starting to... ."

"First of all you know your job is a little big b****** if you can't explain it to a kid. He understands what policeman and doctors and firemen do, but actors, you like: 'Well we help tell stories, like the stories in your books but we act them out.' That's sort of what we've landed on as an explanation."

However, Radcliffe's son is starting to realise his dad might be famous after seeing an advert for his TV show The Fall and Rise of Reggie Dinkins.

"And I had left the room and apparently I popped up in the corner of the screen and he just went: 'Dada!' with a tone of: 'I'm not crazy right?'

"And a bunch of kids in our building, that was there first time seeing me [on TV]. Our friend's daughter, who is like five, was like: 'I saw you on TV, what were you doing there?' ... It was very funny."

Radcliffe starred in eight Harry Potter films. He admitted that he might be able to keep his most famous role secret from his son for a bit longer as the youngster may end up getting his first glimpse of the wizard's world by watching the new TV show. It features a new cast of young actors instead of his dad's movies.

He added: "As much as I can do to just be his very uncool, unimpressive dad for as long as I can is the goal."
