Information about the Angry Birds 3 movie
Compared to the first movie, the lower box office success of the second movie reduces the possibility of the producers making a third movie. In addition, considering the old popularity of the Angry Birds game has decreased over time and the competition in the market from similar animated movies, the likelihood of Angry Birds 3 seems quite low.
It seems unlikely that the producers will make a decision to make a new sequel considering the decrease in revenue and budget requirements.
