Rosie Grier's football days ended when he had too many permanent injuries to his legs, though it didn't stop his acting career. However, here, the story required some hard running action scenes, but they show him painfully straining at a limping trot that anyone could outpace. Through editing magic, he always catches up, though.
Second appearance of Rosie Grier as modern-day bounty hunter Salathiel Harms, he was previously featured in Season 3, "Bad Dude" (1976).
