"Star Trek Beyond" underperformed at the box office for several reasons. Firstly, it faced stiff competition from other blockbuster releases in 2016, including "Ghostbusters" and "Captain America: Civil War." Additionally, the marketing campaign was considered weak, failing to capture the audience's attention effectively. The film also diverged somewhat from the traditional Star Trek formula, which may have alienated some long-time fans. Lastly, the tragic death of actor Anton Yelchin, who played Chekov, added a somber note that may have impacted viewer interest.

Chris Pine was initially set to reprise his role as Captain James T. Kirk in "Star Trek 4," but negotiations for his return fell through due to contract disputes and salary disagreements. Pine, along with other cast members, was reportedly unhappy with the proposed terms, which led to uncertainty about the film's development. As a result, the project has faced delays and changes, impacting Pine's involvement in the sequel. Ultimately, this resulted in his absence from the film's planned production.
