What is the context of The Truman Show

Christof, the creator of a television show called "The Truman Show," informs a documentary-style camera that even though everything around Truman is fake, his life and emotions are genuine. Actors Hannah Gill and Louis Coltrane, who play Truman's wife and best friend, respectively, support Christof's statement. Meanwhile, Truman Burbank (Jim Carrey) has no idea that 5,000 hidden cameras document his entire life, making him one of the biggest TV stars in the world. He also does not realize that Seahaven Island, where he lives, is a giant television studio under a dome, controlled entirely by Christof and his production team.
