In a statement, Mr. Kurtzman, an executive producer on the project, said: “With overwhelming joy, it’s a privilege to welcome Sir Patrick Stewart back to the ‘Star Trek’ fold. For over 20 years, fans have hoped for the return of Captain Jean-Luc Picard and that day is finally here. We can’t wait to forge new ground, surprise people, and honor generations both new and old.”

It is unclear what part of Picard’s story will be explored or when the project will begin production. It is also uncertain whether other “Next Generation” cast members will be a part of the project. Mr. Stewart, Rod Roddenberry, Akiva Goldsman, Heather Kadin, Trevor Roth, James Duff and Michael Chabon are also listed as executive producers.

And while “Star Trek” fans are excited about Mr. Stewart’s return to the franchise, the move comes with a great deal of risk. Films involving “The Next Generation” have been met with mixed reviews, and critics accused the film writers of mangling Picard’s character in comparison with the portrayal on the television show.

But at a moment when several legacy television shows have returned or are in the process of coming back to the screen, perhaps it is fitting that one of the most famous roles in science fiction history will return.

“During these past years, it has been humbling to hear many stories about how ‘The Next Generation’ brought people comfort, saw them through difficult periods in their lives or how the example of Jean-Luc inspired so many to follow in his footsteps, pursuing science, exploration and leadership,” Mr. Stewart said. “I feel I’m ready to return to him for the same reason — to research and experience what comforting and reforming light he might shine on these often very dark times.”
