Thursday’s issue of Australia’s Herald Sun talked about a tour of the Leavesden Studios lot that the Sun went on during Half-Blood Prince filming last year. Here is some thanks to SS:

Rupert Grint (aka Ron Weasley) and Emma Watson (Hermione Granger) aren’t among that team today — they’ve headed north for an outdoor location shoot — but the boy wizard himself, Daniel Radcliffe, is present for duty in the place he’s called his second home since before he was even a teenager (he turns 20 next month).

Radcliffe’s not in this scene, but he’s happily watching what Jim Broadbent, who makes his Potter debut in the Half-Blood Prince as Horace Slughorn, does with his several go-throughs.

Slughorn is greeting guests, including Luna Lovegood (played by the wonderfully eccentric Evanna Lynch) dressed up like a silver Christmas tree, and with each take Broadbent mixes it up — easy stuff for a veteran of his status.

‘‘I wasn’t in the first shot this morning but I went down to watch it just ’cos . . . I’m just interested in it and I want to see how other people act together. It’s about learning, for me,’’ Radcliffe says.

‘‘I like wandering round. Sometimes I go and play table tennis or I’ll read or I’ll play a computer game. But most of the time here I’m on set, so there is not a huge amount of down time.’’
