Trolltider – the legend of the Bergatrollet is SVT's Christmas calendar 2023, directed by Lisa Farzaneh from a script by Ola Norén and Roland Ulvselius. The series is a "reboot" to SVT's Christmas calendar Trolltider from 1979 with partly the same characters but a new story.

In 'Burn All My Letters', author Alex Schulman confronts his deep-seated anger after a fight with his wife. This anger has been passed down through generations, leading to family conflicts and vendettas. The story follows Karin and Sven Stolpe, and Karin's affair with Olof Lagercrantz in the 1930s, which has lasting consequences over the decades.
