Brett Cullen | Walt Riggins
Walt Riggins is the father of Tim and Billy Riggins. He appeared in the first season of Friday Night Lights. The rough and tough nature of the man was what made viewers question his ability to be a father, and our suspicions turned out to be true. After four episodes, Walt was gone and never heard from again.
What eventually led to his departure from the show, or rather why he had to leave Dillon, were the accusations that he had stolen a camera from the Dillon Panthers. Despite his pleas, the spotlight was on him as the main culprit, and the accusations turned out to be true.
