Some amateur sleuths argue that the 1962 escapees survived and lived in South America until the late 1970s. A fringe theory, circulating on internet forums since the early 2000s, claims that one of the Anglins was spotted in Brazil in 1979. The U.S. Marshals Service, which took over the case in 1979 (a coincidence of timing), has dismissed these claims as unverified.
The film's tension builds slowly but surely, as Morris and his accomplices meticulously plan and execute their daring escape, utilizing their skills and intelligence to outsmart the prison's authorities. The suspense is amplified by the eerie and foreboding atmosphere of Alcatraz, which is captured beautifully through Siegel's atmospheric direction and the cinematography.
The escape was not discovered until the next morning, when guards conducting the headcount realized that three inmates were missing. A massive search effort ensued, with the FBI, Coast Guard, and local authorities scouring the Bay and surrounding areas. The search continued for weeks, but no bodies or signs of the inmates were ever found.
For months, Frank and his brothers in arms—the Anglin brothers, John and Clarence, and the carpenter Allen West—had been conducting a silent war against the fortress. They weren't fighting the guards with fists or knives; they were fighting them with patience and ingenuity.
