The question of how much revenue Ready Player One would have to generate in order to warrant a sequel is a difficult one to answer. It ultimately depends on a variety of factors, including the production budget of the first film, the marketing costs, and the overall financial goals of the studio.
In order to understand the potential for a Ready Player One sequel, it is important to look at the financial success of the original film. Released in 2018, the movie had a production budget of $175 million, making it one of the most expensive films ever made. However, it was also a critical and commercial success, earning over $582 million at the worldwide box office.
With such an impressive box office performance, it seems likely that a sequel to Ready Player One would have a strong financial incentive for the studio. However, it's important to remember that there are a lot of factors that go into the decision to greenlight a sequel, including the cost of production, marketing, and distribution.
Ultimately, the decision to make a sequel will depend on a variety of factors, including the financial performance of the original, the willingness of the creative team to return, and the overall vision for the franchise. While it's impossible to predict exactly how much money would be required to warrant a sequel, it seems likely that a follow-up to Ready Player One would need to perform well at the box office and garner strong critical reception in order to justify another big-budget production.
