The still untitled The Boys spin-off has added Lizze Broadway (Bones, NCIS) and Jaz Sinclair (Chilling Adventures of Sabrina, The Vampire Diaries) to the cast, according to Variety. The spin-off was fast-tracked suddenly last year on the strength of the Prime Video series, which isn't a total shock given the original series was an adaptation of an already successful comic book series.

Broadway and Sinclair are the first announced cast members for the spin-off, which will take place at a college for young superheroes, run by the ominous Vought International--the evil corporation that controls The Seven. The spin-off has previously been described as "an irreverent, R-rated series that explores the lives of hormonal, competitive supes as they put their physical, sexual, and moral boundaries to the test, competing for the best contracts in the best cities. Part college show, part Hunger Games--with all the heart, satire, and raunch of The Boys."

All that's known about the new cast members is Sinclair will play Marie, and Broadway will play Emma--both young superheroes. The spin-off has not yet officially been ordered to go to series, but cast members being announced is a good sign that it's a likely bet.
