The third and final collaboration between director Mike Nichols and screenwriter Buck Henry, following The Graduate and Catch-22, The Day of the Dolphin, is a true one-off. A science-fiction thriller filmed in the Bahamas, and adapted from Robert Merle's best-selling novel, the film concerns a scientist (George C Scott, Hardcore) who is teaching dolphins to speak but finds himself embroiled in a shadowy government plot to assassinate the US president.
