Eastwood plays Frank Corvin, a retired NASA engineer called upon to save a failing Russian satellite. "Space Cowboys" was one of the year's commercial hits and was generally well-received, with a 79% rating at Rotten Tomatoes. The film received a moderately favorable review from Roger Ebert, who remarked, "it's too secure within its traditional story structure to make much seem at risk—but with the structure come the traditional pleasures as well... Eastwood as director is as sure-handed as his mentors, Don Siegel and Sergio Leone. We leave the theater with grave doubts that the scene depicted in the final feel-good shot is even remotely possible, but what the hell; it makes us smile."
