six penstock tunnels, each about in diameter. The design of the penstocks and auxiliary spillways using these tunnels has proved to be an issue, however. Cavitation problems have damaged these tunnels in the past. In popular culture A 30-minute documentary about the dam, La presa de Aldeadávila, was produced by Iberduero (the power company that built the dam) in 1963. Several scenes in the 1965 David Lean film Doctor Zhivago were filmed at the Aldeadávila Dam. The dam's famous spillways were opened for the filming, and are shown in the motion picture open at full force. Another scene depicts workers walking into one of the dam's enormous tunnels. The final scenes of Antonio Mercero's 1972 film, La cabina (The Telephone Box) were also filmed inside the dam. Terminator: Dark Fate filmed a scene at the dam.
