The makers of Bahubali left the audience wondering why Katappa killed Bahubali. They later announced that they would be making Bahubali 2 to answer this question. This suggests that if a story ends with something unresolved, there is a high chance of a sequel.
The makers of Jawan have also hinted at a sequel. At the end of the film, Shah Rukh Khan's character, Azad, receives a letter from Sanjay Dutt's character, Madhavan Naik. The letter mentions another mission, which suggests that there is more to the story.
The success of Jawan at the box office is another reason why a sequel is likely. The film earned over ₹130 crore on its opening day, making it the highest-grossing Bollywood film on its opening day. The makers of Jawan would be missing out on a great opportunity if they did not make a sequel.
Coming back to Jawan, it is a very good film and has received positive reviews from both critics and audiences. If you haven't watched it yet, I recommend going to the theater near you and enjoying the film.
