In Alien, the part of Kane was originally to be played by British actor Jon Finch. On the first day of shooting however, Finch had a severe attack of diabetes and had to be taken to the hospital. In a rush to replace him, Ridley Scott sought out actor John Hurt. Hurt was initially unavailable due to a project that he was scheduled to work on in South Africa. As it turned out, Hurt was denied entrance into South Africa because the South African authorities had mistaken him for a political activist named "John Hurd", who had developed a reputation for his outspoken views against Apartheid. Unable to work in South Africa, Hurt then became available to work on Alien.
