The speech and interviews:
Fantastic Beasts and Where to Find Them
"Thank you for this star. It is incredibly surreal and still slightly overwhelming and hasn't really sunk in yet. "A few months ago I was walking along here with a couple of friends and was slightly in awe and slightly overwhelmed by the names I was going to be joining. "Growing up in England, when you hear the word Hollywood, right after you picture the sign on the hill, you picture these stars. It feels a very long way from when you grow up in Fulham to this."
(regarding the crowd of supporters)
"The fans of the Harry Potter films are unique and amazing and wonderful and still, six years on since I finished them, I am constantly being amazing by their passion, their curiosity and by the fact they are interested in so many other things than Harry Potter and that is a curiosity that was fostered by Jo Rowling and passed on to all of you."
(tribute to his parents)
"I never thank them and I'm not going to look at them because that would be a mistake for all of us. I want to thank my mum and dad, who really do not like this kind of attention so will probably be getting embarrassed right now. "I have to thank them because you are the best parents. It was a crazy thing that we embarked on as a family 16 years ago but we made it and I made it thanks to you."
