The upcoming Outlander prequel series, Outlander: Blood of My Blood, is expected to continue the success of its parent show with its unique storytelling and romantic elements. Based on the novels by Diana Gabaldon, the spinoff will delve into the epic romance of Jamie's parents, Ellen MacKenzie and Brian Fraser, going beyond the original material. Actor Sam Heughan has expressed interest in a possible cameo in the prequel, although incorporating that may be challenging since Jamie cannot time travel. The release date for Outlander: Blood of My Blood is uncertain due to production delays caused by the ongoing Hollywood strikes.

The official cast has not been announced, but it is expected to focus on the younger versions of familiar characters. Matthew B. Roberts, the showrunner of the original series, will also be involved in the spinoff. The story will revolve around the forbidden love between Brian and Ellen in a time when marriages were strategic rather than based on love.
