Harry Lennix is guest starring on the March 6 episode of the CBS series Boston Blue, marking an on-screen reunion with his former ER co-star Gloria Reuben. Lennix, who played Dr. Greg Fischer on ER, says it was "exciting to have the sense of continuity" with the work he and Reuben did on the medical drama nearly 30 years ago. In the Boston Blue episode, Lennix plays Judge Eli Robinson, a former lover of Reuben's character, District Attorney Mae Silver.

Why it matters

The reunion between Lennix and Reuben is a nostalgic moment for fans of ER, one of the most popular medical dramas in television history. Their characters' romance on ER was groundbreaking at the time, as Reuben's Jeanie Boulet was one of the first HIV-positive characters portrayed on a major network series.

The details

Lennix and Reuben first worked together on ER in 1997, when Lennix guest-starred as Dr. Greg Fischer, the love interest of Reuben's character Jeanie Boulet. Now, nearly three decades later, the two actors are reuniting on the set of Boston Blue, where Lennix is guest-starring as Judge Eli Robinson, a former lover of Reuben's District Attorney Mae Silver. Lennix says the reunion felt like "picking up where we left off" and that he was "over the moon" to work with Reuben again.
