Pre-dating The Quest by one year was another failed TV Western series featuring a star of The Virginian. Barbary Coast (1975) was set among San Francisco’s Barbary Coast in the 1880s. Doug McClure played casino owner Cash Conover, friend to undercover federal agent and master of disguise Jeff Cable (William Shatner).
Unlike Matheson and Russell who complimented each other on The Quest Doug McClure and William Shatner lacked chemistry and the show soon found itself losing viewers. A clumsy mix of The Wild Wild West and Mission Impossible, Barbary Coast was yet another victim of early cancellation with only 14 episodes completed.
