However, viewers were left astounded by the season three finale “A House Divided”, which saw JR shot in the chest by an unknown figure.
The season was left on a cliffhanger, with viewers forced to wait eight months before the show returned and gave them an answer.
It’s been 40 years since one of the biggest TV events of the 20th century took place, as millions of people around the world tuned in to find out who shot JR on Dallas.
Many people around the world bet on the outcome, but actor Hagman claimed that neither him nor the cast knew who had actually shot JR when the finale aired.
