17 Harry Potter Stars Wish J.K. Rowling a Happy Birthday

From Rupert Grint to Imelda Staunton, stars who took the story to the big screen write for TIME

July 31 is the most famous fictional birthday in contemporary literature: Harry Potter’s birthday. Strange, magical, sometimes wonderful things tend to happen on that day. It’s also his creator, J.K. Rowling’s birthday. And since we couldn’t reach Harry, Ron and Hermione to wish her many happy returns (they must be hiding under their invisibility cloak), we did the next best thing: we invited the stars of the HP movie franchise to send her birthday greetings. As far as we know, none of these messages were delivered by owl.

    The Happiest of Birthdays, Jo.

    A breeze for the supreme Time-traveller.

    Love from Alan Rickman.

    Warner Bros. Imelda Staunton as Dolores Umbridge in Harry Potter and the Order of the Pheonix released on July 11, 2007.

    Dear Miss Rowling,
    On the occasion of your birthday I trust you will be clothed in delicious pink garments surrounded by plates of purring kittens.
    These wishes come By order of Dolores Umbridge

  • Robbie Coltrane

    Harry Potter Stars JK Rowling Birthday
    Peter Mountain—Warner Bros. Robbie Coltrane as Hagrid in Harry Potter and the Chamber of Secrets released on Nov. 15, 2002.

    Happy Birthday! Jo. You don’t look a day over 40; everyone knows what a wonderful writer you are, and how much you did to get children to read books, and your charity work, but they perhaps don’t know that in private you are very very funny. Perhaps you could celebrate your half century by writing a hilarious film. Perhaps, starring, I don’t know, a large Scottish man. Have a great day, you so deserve it, all my love, Robbie C. XX

    Robbie Coltrane played Rubeus Hagrid in the Harry Potter series.

  • Natalia Tena

    Harry Potter Stars JK Rowling Birthday
    Warner Bros. Natalia Tena as Nymphadora Tonks in Harry Potter and the Order of the Phoenix released on July 11, 2007.
    So where the hell do I start? 50 years ago, a someone was born that has done what most of us dream of. She has made this little planet of ours a better, happier place and will leave a legacy that means that, that joy will continue to exponentially grow, generation by generation. I’m saying something everyone has said and will continue to write and say. Still it needs to be said and written.Let’s face it, we all want to live in her world, identify individually with the characters and the magic wielded there which seems to be like a fantastic extension of our tangible world.

    She has made children turn back to the loving medium of books, feel the power of a page and fly behind the eyes of witches and wizards.

    She has made me remember feeling young.

    She deals with the ultimate anchor of our lives: death, and introduces it to children in a healthy, aware way that can propel them to find a concrete way of dealing with it.

    She makes me laugh.

    Thank you and I’ll be having pint of butter beer (JK, please tell us the recipe!) here’s to another 50 years (can’t believe you’re 50 by the way, you look HOT!)

    I could talk about the millions of lives Jo has enriched whether through the stories and characters she’s created or through the millions of pounds she’s given to charity. She’s a remarkable woman. However, I would like to thank Jo for changing MY life. Without her imagination and her talent I would never have become the man I am today. That’s not even to mention her generosity and loyalty when it has come to supporting everything that I have done in the years since Harry Potter. She’s just a wonderful human being and I consider myself so privileged and honoured to call her a friend. Happy birthday, Jo.

    Matthew Lewis played Neville Longbottom in the Harry Potter films. He will next be seen alongside Emilia Clarke and Sam Claflin in the movie adaptation of Jojo Moyes’ Me Before You.

    You gave me the greatest gift of all, your trust and support, when it came time to bring your world to life on the big screen.

    The three films we worked on together were the most creatively fulfilling years of my cinematic life. I will always cherish the countless hours you, David Heyman, Steve Kloves and myself spent huddled in a room, working so intensely on each film.

    Thank you for everything. May you have the most wonderful and perfect birthday celebration.

    See you along the way,

    Dearest Jo,

    When we first met in person it took me a few frozen moments to recognise you. My reaction should have been instant given the level of mega-fan obsessiveness I’d proudly cultivated for years or by the impressive entourage of smiling faces that trailed in after you, or by the heavily expectant silence that was quickly becoming awkward. But it took me several seconds longer than was normal to have the appropriate jumping /squealing /hyperventilating fangirl fit because it seemed impossible to fathom that everything I loved – a vast universe, the very buildings and sets we were standing on, the hundreds of people milling about with one creative vision in mind – all of it, had come from the lovely, glowing, blonde woman before me who was on the small side of human and the miniature side of SuperWoman.

    You squatted down by the make up chair to chat and it was very hard to piece words together into sentences because I wasn’t sure whether I was talking to a person or a spiritual portal connected to hundreds of different voices, souls and energies, all of whom I wanted to speak to and ask the geekiest of questions. But we continued to talk and it was both marvelous and incredible to realise you were human, to see your warmth, curiosity, the generous gaze and genuine interest you afforded each person you encountered. By the time we parted (rather, when I was dragged sullenly back into tutoring…) you left me with the distinct impression that small, sensitive ladies can change the world.

    It’s been ten years and you are still reminding me of this. I’ve come to realise that it was that precise humanity and warmth I experienced when I met you, that curse of caring too much and of feeling too many feelings and that uncontainable imagination that can see far beyond what is real, that make you such a force of change and – and I don’t care what disclaimers you make about being Hufflepuff deep down – such a fierce, bold Gryffindor! You inspire me endlessly in your art, your activism and your sassy Twitter comebacks so please keep loving and caring and imagining as hard as you do.

    Love you. Happy 50th!! Have the most Magical Happy Birthday ever!!

    Jo,

    It’s hard to overstate what you’ve given to a whole generation of people. To this day I still feel absurdly privileged to have been along for part of the ride.

    Happy 50th. You don’t look it.
