The veteran actor, who played Sirius Black in the wizard movie franchise, often shared father-and-son style chats with the teenage Radcliffe on set.

And he's revealed the youngster once asked for advice on how to charm women when he was nervous about a big date.

Oldman tells Britain's Live magazine, "Daniel's a lovely lad. When we did (Harry Potter and) the Prisoner of Azkaban he said to me, 'I'm going away for the weekend. I'm going to this girl's house and I really like her.' It might have been his first real girlfriend.

"He was sleeping over; obviously her parents were there, but Daniel said, 'I'm quite excited. Have you got any advice?'. He was 13 or so - we still laugh about that. I saw him about a year ago and we had a cup of tea together."
