The untitled Han Solo film coming in 2018 will reveal how the titular character came to carry his iconic name. Meanwhile, Woody Harrelson takes up another mentoring role in the film.

Directors Phil Lord and Christopher Miller are working on an untitled Han Solo film that is set to premiere in 2018. The film, temporarily dubbed as "Han Solo: A Star Wars Story," follows the story of a young Han Solo, to be portrayed by Alden Ehrenreich.

At the recent USC tech conference, Disney CEO Bob Iger revealed that the film will follow Han when he was 18 to 24 years old, Entertainment Weekly confirmed. Iger added that the story behind Han Solo's name will also be revealed.

"There were a few things that happened [that were] significant in Han Solo's life, like acquiring a certain vehicle and meeting a certain Wookiee, that will happen in this film. But you'll also discover how he got his name," Iger explained.

Meanwhile, Harrelson has been added to the cast of the upcoming Han Solo spin-off in another mentoring role, Slashfilm confirmed.

Harrelson played mentor to Katniss (Jennifer Lawrence) in the "Hunger Games" film series as Haymitch Abernathy. In the Han Solo film, he will be both a criminal and a mentor to the titular character.

"I play a guy named Beckett, who's kind of a criminal and a mentor to Han," Harrelson revealed while guesting at "The Tonight Show Starring Jimmy Fallon."

According to The Hollywood Reporter, Donald Glover is part of the film's cast as the young Lando Calrissian, from whom Han Solo will acquire his ship, the Millenium Falcon. Emilia Clarke from "Game of Thrones" will also star, alongside Thandie Newton, Phoebe Waller-Bridge, and Ian Kenny from "Sting Street."

"Han Solo: A Star Wars Story" is slated to premiere on May 25, 2018.
