Pålsson used to be the lead singer in an indie rock group, ÅR&DAR.[6]
He played Mads in Armando Iannucci’s space sitcom Avenue 5 who was a gormless but good-looking crew-member. Initially he was supposed to be an extra, but was given a part and a name. Pålsson went for the role as he admires Iannucci so much.[7]
He plays Kurt Wallander in the 2020 Netflix/Yellow Bird production Young Wallander.[8] In an interview in The Guardian he explained he was able to connect with the character of Wallander as his family are from the same area of Sweden. He is also the only Swedish actor in the series.[7]
He had a main role in the Swedish crime drama series Before We Die.
