ridley scott was so nervous during an early screening of alien, that he had to get a little drunk during it /

Back in 1979,Alien was not the horror sci-fi classic it is nowadays. In fact, 20th Century Fox was totally unsure of what up-and-coming director Ridley Scott had made. You must remember that he was pretty much an advertisement director up until that point with one feature to his name, and the 19th-Century period piece, The Duellists (1977).
