Professor Broadbent
Alternativa 3 es un programa de televisión transmitido en el Reino Unido en 1977 que consiste en un documental ficticio al estilo de la producción radial "La guerra de los mundos" de Orson Welles. El programa aparenta ser una investigación periodística acerca de extrañas desapariciones de científicos británicos y que casualmente termina descubriendo un plan para construir bases secretas en el espacio con la finalidad de escapar de una inminente catástrofe climática en la Tierra.
La idea original de la producción era transmitir el programa el "Día de los bufones de abril" de 1977, pero por razones comerciales la transmisión fue postergada hasta junio aunque los créditos finales señalan el primero de abril como fecha del documental. Los créditos finales también incluyen los nombres de los actores y una entrevista a un falso astronauta estadounidense.
