The actor who played Pennywise the clown in the Stephen King's It movies has signed on to star as another madman--but this time a real one. Netflix has announced that Bill Skarsgard will play the Swedish gangster Clark Olofsson in a six-episode Swedish language drama series called Clark.

Among other things, Olofsson is known for his association with the term Stockholm syndrome. During the Norrmalmstorg bank robbery in 1973, Olofsson was allowed out of prison to help negotiate the release of hostages. The hostages bonded with Olofsson and the captors, and subsequent studies on the case led to the popularity of the term Stockholm syndrome.

Oloffson has been convicted of numerous crimes, including attempted murder, drug trafficking, and assault.
