Tom Hardy, Ryan Gosling, Megan Fox and more shocking exits

Hopper was cast as Christof, the sinister puppet master at the centre of ‘The Truman Show’, but lasted just one day before being fired after the producer and director agreed he was not right for the part. Hopper later explained, “Scott Rudin, the producer, had agreed with the director that if he didn’t like what I did after the first day’s dailies, then he would fire me. And they fired me.” Ed Harris stepped into the role and received an Academy Award nomination for best supporting actor, making it one of the more remarkable turnarounds in Hollywood casting history.
