The Telegraph has a new interview with Potter production designer Stuart Craig, where he discusses his career, his work on the series, as well as the detail he has put into items such as the Golden Snitch and the Weasley Clock. Of note was as an emotional moment that occurred for him recently on set.
“The last time I cried was a few days ago when we filmed the death of Alan Rickman's character, Snape. It's quite difficult to cry in rushes — where we watch the previous day's work — but he is an extraordinary actor and he dies an extremely good death.”
Thanks to Sam for all her help (getting the paper, scanning and e-mailing) and Violet for the tip!
