10 Buffy The Vampire Slayer Actors Who Went On To Star In Supernatural

10. Jack Conley

Jack Conley joined Buffy The Vampire Slayer in the season two episode "Phases" as werewolf hunter Gib Cain.

Sporting a necklace of werewolf teeth from previous kills, Cain arrives in Sunnydale tracking the newly transformed Oz (Seth Green), hoping to sell his pelt on the black market. After just a single episode of derring-do, in which the Scooby Gang save Oz, break Cain's rifle and send him off with his tail between his legs, Conley left the show, never to be seen again.

His brief tenure on Buffy was a sign of things to come, as Conley appeared in just a single Supernatural episode (season four's "Yellow Fever") as eccentric neat-freak Sheriff Al Britton. As the Winchesters unfurl their latest case, it becomes apparent the Sheriff is embroiled in a murder cover up, and as he threatens the boys in an attempt to cover his back, his heart gives out and, well, the rest is history.

Though his time on both shows was short, bit-parts seem to be Conley's bread and butter, as he has popped up as a one-off in everything from Freaks & Geeks to The West Wing. Conley also held a longer-term role (for him) of eight episodes in Buffy spin-off series Angel, as nigh-invincible Granok demon Sahjhan.
