Richard Kiley (March 31, 1922 – March 5, 1999) was an American actor. He is very well known for his voice work in documentaries as well.
In Jurassic Park, John Hammond had hired Kiley to narrate the main tour. In the novel, Ed Regis announces, “That’s Richard Kiley. We spared no expense!” In the film, this is changed to Hammond speaking from the control room.
