On October 21, 2018, the Galapremier of Halvdan Viking took place at Rigoletto in Stockholm. Halvdan Viking takes us back to the viking period and is written by the well-known author who is also behind all the LasseMaja books, Martin Widmark. Guests were invited to good chocolates, books from the Halvdan series and good snacks to bring along during the film. Both adults and the small ones wanted to see the movie and it was a crowded cinema with lots of curius vikings.
