Iron Man (2008)
Box office top-notcher Iron Man is one of the biggest movies with the highest gross income on its opening weekend of 2008. The creation of this successful superhero film took about 18 years to develop, starting with Universal Studios buying the rights of Iron Man’s development on the big screen. Due to its low budget, the production was not pushed through, instead the rights were transferred to 20th Century Fox in 1996. A year after, actors such as Tom Cruise and Nicolas Cage expressed their interest in playing the main character Tony Start who was later on portrayed by Robert Downey Jr. Quentin Tarantino was then approached in 1999, asking if he could direct the movie. Then, New Line Cinema eventually acquired the rights from Fox, and after a long process of preparations and transfers, the rights were finally given back to Marvel Studios, and they had to work again from scratch in producing this big film.
