So I posted a bit back that I was bored. Then I got a rather long comment discussion with
During that discussion I started pointing out all the SPN cast members and extras that had appeared in BSG. Both shows are filmed in Vancouver BC and I think I read somewhere that they used the same casting company. So I started listing all the ones I could think of.
So here's the list so far. In no particular order.
| Actor | SPN | BSG |
| Callum Keith Rennie | Roy (the backwoods guide) Wendigo 1x2 | Leoben Mini-series, S1-S4 |
| Donnelly Rhodes | Shaw (the old man who survived a Wendigo attack as a child) Wendigo 1x2 | Doc Cottle S1-S4 |
| Andrew McIlroy | Mystery Spot Guy Mr. Karpiak Mystery Spot 3x11 | Quorum Member Jacob Cantrell 4x3, 4x4, 4x7, 4x8 |
| Dominic Zamrogna | Beau (one of the vampires) Dead Man's Blood 1x20 | Jammer S1-S3 |
| Samantha Ferris | Ellen S2 | Deckhand Pollux 3x15, 3x16 |
| Leah Cairns | Julie Crossroad Blues 2x8 | Lt. Margaret "Racetrack" Edmonson S1-S4 |
| Vincent Gale | Evan (Julie's husband) Crossroad Blues 2x8 | Peter Laird Razor & 4x10 |
| Tricia Helfer | Molly McNamara Roadkill 2x16 | Six Mini-Series, S1-S4 |
| Barclay Hope | Professor Cox Tall Tales 2x15 | Caprica One Pilot Mini-series |
