Daniel Radcliffe's young son is blissfully unaware that his father played the famous character Harry Potter. The 36-year-old actor, who has a son turning three in April with his partner Erin Darke, shared insights about his attempts to explain his profession to the little one.

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

He humorously added, "First of all, you know your job is a little big b****** if you can't explain it to a kid. He understands what policemen, doctors, and firemen do, but actors? You have to say: '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."

Daniel noted that his son is beginning to grasp that his dad might be famous after seeing an advertisement for his TV show, The Fall and Rise of Reggie Dinkins.

He elaborated, "We were watching the Olympics, and the Reggie Dinkins show is on the same network... It was advertised heavily during the Olympics — apologies to everyone who had to watch a lot of the trailer.

"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?'

"A bunch of kids in our building saw me for the first time 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 ..."

Daniel, who starred in eight Harry Potter films, expressed that he might be able to keep his most famous role a secret from his son a little longer, as the child may end up discovering the wizarding world through the new HBO show featuring a fresh cast of young actors instead of his father's films.

He concluded: "I think there's a world where my son watches the HBO show of Harry Potter now instead of the films, and I'm also happy with that. As much as I can do to just be his very uncool, unimpressive dad for as long as I can is the goal."
