On Sept. 27, Warner Bros. Pictures is live streaming the London premiere of Lady Gaga and Bradley Cooper's 2018 remake of "A Star Is Born," with the event at Vue West End in Leicester Square scheduled to start at approximately 6:30 p.m. British Summer Time/1:30 p.m. Eastern Daylight Time. The movie, which is set to open in cinemas on Oct. 5, has been getting rave reviews since it had its world premiere Aug. 31 at the Venice International Film Festival. The film had its Canadian premiere at the Toronto International Film Festival on Sept. 9 and had its U.S. premiere in Los Angeles on Sept. 24.

As previously reported, select AMC Theaters with Dolby Cinema screening rooms will have a sneak preview of the movie on Oct. 2.  Ticket purchases to the special Oct. 2 screenings will include a download of the A Star Is Born soundtrack, which features all songs performed by Cooper and Lady Gaga. Cooper is also one of the movie's screenwriters and producers.

In "A Star Is Born," Cooper (who makes his directorial debut) plays Jackson Maine, an alcoholic country star, and Lady Gaga plays Ally, an aspiring pop/rock singer. They fall in love, and Jackson helps Ally with her career. When she becomes famous, it complicates their relationship, which was already troubled by addiction and insecurity issues.

There is significant buzz that "A Star Is Born" will be a major contender at the Oscars and other award shows that honor movies and music. Because the soundtrack to "A Star Is Born" is being released on Oct. 5, the soundtrack won't be eligible for Grammy Awards until the 2020 Grammy ceremony. Sept. 30 is the cutoff date for music to be released in time to be eligible for the following year's Grammy ceremony.

Several clips from the movie show that one of the key scenes is when Lady Gaga's Ally character sings an early version of the song "Shallow" to Cooper's Jackson character when they are sitting in a convenience-store parking lot."Shallow," which is already being touted as a potential award-show nominee for Best Original Song, was written by Lady Gaga, Mark Ronson, Anthony Rossomando and Andrew Wyatt. Lady Gaga and Benjamin Rice produced the song. "Shallow" is also the song that Jackson's character sings at a concert and coaxes a reluctant Ally to join him on stage to perform the song. It's another major turning point in their relationship.

Lady Gaga, Cooper and "A Star Is Born" songwriters Ronson and Lukas Nelson sat down for a group discussion about the making of the music in a promotional video released by Warner Bros, Pictures. Lady Gaga said in the discussion, "We were writing 'Shallow' from the point of view of Ally … When I was writing songs for the film, I had to think of Ally as if she wasn't me." Ronson added, "I had no idea it was going to be part of the narrative. You sang the opening line, and I really did get chills."

In interviews, Cooper has said that he spent 18 months training to be a singer and guitar player. (All of the songs in the 2018 "A Star Is Born" are performed live.) He worked with coach Tim Monich, a well-known Hollywood voice coach who trains people in dialect and singing. In another part of the group discussion, Cooper talked about his preparation for the Jackson character as an authentic musician, saying that he lowered his voice by an octave for the Jackson character. Cooper added, "I had a sound in my head of what I wanted Jackson's guitar to sound like, and it was heavily influenced by Neil Young. His guitar strumming never floated around the [guitar] neck. It attacked the neck."

Nelson, who is a son of Willie Nelson, leads the band Lukas Nelson & Promise of the Real, which has toured with Young and plays Jackson's band in the movie. Lukas Nelson said to Cooper, "I remember thinking that you were always a musician." Cooper added, "There is no Jackson Maine without Lukas Nelson." The movie opens with Jackson performing "Black Eyes," a song written and produced by Cooper and Lukas Nelson. 

The cast of 2018's "A Star Is Born" also includes Sam Elliott as Jackson's brother/manager Bobby; Dave Chappelle as Jackson's friend Noodles; and Andrew Dice Clay as Ally's father Lorenzo. A clip from the movie shows Noodles finding Jackson passed out on a street in an alcoholic stupor and expressing concern to his troubled friend. Another clip from the movie shows Jackson performing "Maybe It's Time," a song written by Jason Isbell and produced by Cooper and Rice.

The Cooper-directed "A Star Is Born" is the fourth "A Star Is Born" movie. In the original 1937 "A Star Is Born" film, the couple was played by Fredric March and Janet Gaynor, who both portrayed actors in the movie. In the 1954 "A Star Is Born" film, James Mason played a fading movie star, while Judy Garland played a singer. In the 1976 "A Star Is Born" movie, Kris Kristofferson and Barbra Streisand both played rock singers.
