Field of Dreams
From The Big Bang Theory Wiki
Film (1989) in which a man builds a baseball field in his corn field, believing that if he builds it, "he will come". Sure enough, famous historical baseball players appear on his home made field.
Sheldon comes up with the idea of solving the problems in the Middle East by building a duplicate of the city of Jerusalem in the Mexican desert, claiming that the Jewish people will move there, because "it's like the baseball movie, build it and they will come" (0112).
