Get kid bragging rights for, like, the next year and get a sneak preview of the new Horrible Histories. One of our favourite kids TV shows ever gets the establishment mark of approval with a screening of two episodes of the new series, plus a Q&A session with cast members and the series’ producer. This event is probably going to sell out, but it’s worth checking for returns. £6-£11. Sunday May 12, 2pm. More here.
