Simon Pegg has expressed some difficulties about writing the forthcoming "Star Trek" screenplay.

The actor noted that the studio executives had been concerned that the first script for the hotly anticipated movie had been too "Star Trek-y."

He noted that there was a concern that the previous film "Star Trek Into Darkness" had not garnered as much audience as had been hoped and that creating a film that was too focused on the lore of the franchise was not allowing other audiences to take part in the adventure.

"'Avengers Assemble,' which is a pretty nerdy, comic-book, supposedly niche thing, made $1.5bn. 'Star Trek: Into Darkness' made half a billion, which is still brilliant. But it means that, according to the studio, there's still $1bn worth of box office that don't go and see 'Star Trek.' And they want to know why," said Pegg according to IGN.

He noted that one potential solution was to create a standard franchise film and set it in the "Star Trek" universe to add to the appeal for a wider fan base.

The "Star Trek" reboot make $257 million in U.S. box office when it opened back in 2009. Worldwide the film hit the $385 million mark, which was a respectable number to be sure.

The follow-up, "Star Trek Into Darkness," made $467 million globally, but actually faltered in America with a respectable, but disappointing, haul of $228 million.

The third film in the reboot franchise has had some difficulty getting started. Director J.J. Abrams left the franchise after two films to fulfill his dream of directing "Star Wars Episode VII: The Force Awakens." Roberto Orci took over as the helmer, but eventually left the position vacant. Now Justin Lin, director of the original "Fast & Furious" film is slated to take over the franchise.
