Daniel Radcliffe has revealed Sirius Black is his favourite character from the 'Harry Potter' franchise.

The 25-year-old actor explained that although he'd always been a fan of the character, he became especially enamored with Sirius due to Gary Oldman's portrayal of him.

Speaking during his Reddit AMA, the English star was asked to name his favourite Potter character, to which he replied: ''Probably Sirius. Like I always loved the character, and then Gary [Oldman]'s portrayal of him I thought was perfect. Or Lupin, really.

''Any of the characters my dad used to hang out with, other than Wormtail. There was always something about those two guys I loved a lot.''

Radcliffe also thanked his parents for helping to keep him grounded since finding fame.

He reflected: ''I would attribute it to my parents and also to the crew of the Potter films, who were very good at treating us like kids rather than as actors, as they should have done. But yeah, it's hard to say what it comes down to.''

The actor said the issue came into even sharper focus as co-star Emma Watson approached her 18th birthday.

He continued: ''I think when you see that perspective that we all saw at very young ages, you do get an extra level of awareness maybe.''
