A Robotech live action movie was first announced in 2007. Since then, they changed company, and a different director was announced more than once. Yesterday, I saw the new of an Argentine "Andrés Muschietti" taking over the direction of the movie. How many times has the in-production Robotech live action movie changed director already?
Early 2013: The Hollywood Reporter announces that Warner Bros. is in talks with commercial director Nick Mathieu to direct the film.
July 24, 2013: Leonardo DiCaprio turns down a role in Star Wars: Episode VII and has shown interest to star as a main character in the upcoming big screen version of Robotech. Nick Mathieu is directing the movie at this point.
February 4, 2015: Deadline.com reports Gianni Nunori and Mark Canton have selected Michael B. Gordon to write the film's script and are looking at Andy Muschietti to direct it, after some setbacks to production. Obviously, Nick Mathieu is no longer the director.
March 25, 2015: Variety announces that the Robotech franchise has been acquired by Sony Pictures, who views Robotech as a potential film franchise. Andy Muschietti never got the directing role before Sony bought the rights, so at this point the movie has only ever had one director: Mathieu.
April 29, 2015: Deadline reports that James Wan is in talks to direct the film.
June 3, 2015: The Hollywood Reporter reports that Wan is confirmed to direct the film.
July 17, 2017: The Hollywood Reporter reports that Andy Muschietti will direct the film, after Wan drops out to work on Aquaman.
1st Director - Nick Mathieu
2nd Director - James Wan
3rd Director (Current) - Andy Muschietti
It's also worth noting that the deal with Sony hasn't actually been finalised yet, so there's every possibility of it falling through and production getting thrown up in the air again.
