The first and only spin-off of Babylon 5, J. Michael Straczynski's short-lived sci-fi series Crusade had its roots in the B5 television movie A Call to Arms, in which Earth was battling a Drakh invasion at the end of the Shadow Wars. When Crusade begins, the Drakh have released a deadly virus that threatens to wipe out all 10 billion humans living on Earth unless a cure can be found in five years. To take on this monumental task, Captain Matthew Gideon (Gary Cole) is assigned command of the state-of-the-art Destroyer-class ship Excalibur. His crew includes telepath John Matheson (Daniel Dae Kim); pompous but brilliant archaeologist-linguist Max Eilerson (David Allen Brooks); Dureena, a member of the Thieves' Guild and the last surviving member of her species (Carrie Dobro); medical officer Sarah Chambers (Marjean Holden); and technomage Galen (Peter Woodward). Amazon.ca's price is $23.74, with HST the total is $26.83.
