Firefly Reunion on the Way as Summer Glau to Guest Star on Castle


Editor

It’s a day of casting news for the Firefly crew. First it was Jewel Staite on DC’s Legends of Tomorrow series, and now an on-screen Firefly reunion is set for Nathan Fillion and Summer Glau on Castle.

TVLine is reporting that Glau will guest star in the current season’s 14th episode alongside Fillion, who plays the show’s title character Richard Castle, a mystery writer and private investigator. Glau will guest as a rival private eye named Kendall Frost, who competes with Castle on a case in Los Angeles.

It’s no secret that the Firefly cast love to work together in new projects. Adam Baldwin and Gina Torres have previously had guest spots on Castle, and recently most of Serenity’s crew appeared in Alan Tudyk and Nathan Fillion’s crowd-funded web series Con Man. Summer Glau (and Firefly creator Joss Whedon) popped up for memorable cameos in Con Man‘s episode 7.

Castle‘s eighth season returns February 1.
