Daniel Radcliffe is often left impressed when girls use 'Harry Potter'-inspired jokes to try and get his attention.
The 'Harry Potter' star - who denies using the cringe-worthy technique himself - enjoys it when girls try to get his attention using flirtatious jokes inspired by the wizard movie series.
The 25-year-old actor told OK! magazine:
"I don't think I've ever used a chat-up line on a girl. "I have had a couple of fairly cheesy Harry Potter lines done to me but I've always been quite impressed.
"It takes some balls to walk up and say some of the things I've had said to me. I genuinely from the top of my head can't remember what they were, but I just remember being impressed."
Daniel - who is currently dating his 'Kill You Darlings' co-star, Erin Darke, 29 - is set to make his rom com debut in the upcoming picture 'What If' and admitted that although he enjoys making grand heartfelt gestures, he only considers himself to be a "mild" romantic.
He explained: "['What If'] hasn't changed my views on romance.
I was mildly romantic before and I'm probably the same now.
"I've done romantic gestures and big things like that but I don't think that's what a relationship relies on."
