Will Interstellar 2 be released?
There is currently no confirmation or official announcement from Christopher Nolan in this direction. Nolan is generally known as a director who prefers to focus on single-film stories. When we look at his career, it is seen that he chooses to tackle a new subject in each film rather than making sequels.
Therefore, the probability of Interstellar 2 being released is quite low. Considering the director's style and career approach, it would be a more realistic approach to rediscover the depth offered by the current film rather than waiting for a new sequel.
