“Don’t confuse sincerity of purpose with success.” —John Wayne as Captain Karl Ehrlich in The Sea Chase (1955). This year marks the 70th anniversary of the release of The Sea Chase! Did you know this was the last of four films where James Arness starred alongside John Wayne? Their previous collaborations were Big Jim McLain (1952), Island in the Sky (1953), and Hondo (1953). Which of these Wayne & Arness films is your all-time favorite? Let us know in the comments below! Fun fact: Three months after this film's release, Arness would begin his iconic 20-year role as Marshal Matt Dillon on Gunsmoke (1955)—a role that John Wayne personally recommended him for. The Duke even filmed a special introduction for the premiere of the show.
