A victim of his own versatility, Gordon Douglas seemed never to encounter a genre he couldn’t feel comfortable in. His huge body of work embraces slapstick (“Saps at Sea,” 1940, situation comedy (the “Glidersleeve” series, 1942-44), musical comedy (“If You Knew Susie,” 1948),swashbucklers (“Fortunes of Captain Blood,” 1950), science-fiction (“Them!,” 1954), melodrama (“Sincerely Yours,” 1955) and spy spoofs (“In Like Flint,” 1967), with results that are always professional if not personal. But crime films and westerns seemed to bring out the best in him, with their potential for depicting the violent tension between radical individualists and conformist cultures. Douglas is in some ways the anti-Hawks, fascinated by the networks of distrust and betrayal that bind groups together. That theme is particularly evident in “Kiss Tomorrow Goodbye” (1950) and “Only the Valiant” (1951), two films independently produced by James Cagney and his brother William originally released through Warner Brothers, but now available on Blu-ray and DVD from Olive Films.
