None of the HP cast were there except for Devon Murray (Seamus). Which is, as you both said, expected since they didn't want the spotlight taken away from the cast (understandable). Rupert is also busy shooting for a TV show but I was at least hoping he'd attend as he's in the UK anyway. It has been a
long time since we've seen Rupert & Emma together in
anything. The last was the DH 2 NYC premiere back in 2011.
