Maisie Williams and Zach Wyatt made their professional stage debuts last night at the Hampstead Theatre in I and You and guests came along to celebrate the event.

Lauren Gunderson's play, which makes its UK premiere at the north London venue, follows a teenager, Caroline (Williams), stuck in her bedroom with a serious illness when she's visited by a member of her class named Anthony (Wyatt).

Stars including Kit Harington, Richard Madden, Ellie Bamber and Tom Hiddleston appeared at the show to celebrate and party afterwards.

In the WhatsOnStage review it was said that "considering both are making their professional stage debuts (though Williams has a whole saga of Westeros history under her belt as well as a few successful films) the two performances are impressively assured and equally weighted".
