This film along with 1962′s The Manchurian Candidate and 1964′s Seven Days in May are known as director Frankenheimer’s paranoia trilogy.
** Seconds is also known for its connection to American songwriter Brian Wilson of The Beach Boys, who was strongly affected by the film during sessions for the concept album Smile. After arriving late to the theater, he appeared to be greeted with the onscreen dialogue, “Come in, Mr. Wilson,” believing for some time that the film was directly based on his recent traumatic experiences and intellectual pursuits, going so far as to note that “even the beach was in it, a whole thing about the beach.”Wilson soon after ceased Smile recording sessions for the next several decades. The movie reportedly frightened him so much that it wouldn’t be until 1982’s E.T. the Extra-Terrestrial that he’d ever visit a movie theater again.
