“Star Wars: The Force Awakens” director J.J. Abrams and cast members of the film held an event in Anaheim Thursday where a new teaser for the film was released. The teaser was screened at the end of the Star Wars Celebration held at the Anaheim Convention Center. The new sci-fi flick is expected to be the biggest movie of the year.

“The Force Awakens” is the first installment in a new Star Wars trilogy being released by Disney. The entire project has been shrouded in secrecy since it began. However, that has not stopped set photos and plot spoilers from being leaked on the internet. The movie is scheduled to hit theaters on December 18.

Many of the stars of the original “Star Wars” trilogy are returning for the new installment of the series. Harrison Ford reprises his role as Han Solo, Carrie Fisher returns as Princess Leia, Mark Hamill is Luke Skywalker, Anthony Daniels plays C-3P0, Peter Mayhew returns as Chewbacca and Kenny Baker reprises his role as R2-D2. The new installment in the Star Wars franchise also welcomes newcomers John Boyega, Adam Driver, Andy Serkis, Daisy Ridley, Lupita Nyong’o and Oscar Isaac.

Most of the cast attended the event at the Anaheim Convention Center, with Ford being the only notable exception. The 72-year-old actor was severely injured in a plane crash last month and is still recovering. During the event, the cast members spoke to fans from a panel and revealed details about their characters and the film. Boyega is playing a stormtrooper named Finn, but little more is known about the character than that. Isaac is cast as an X-Wing pilot and Ridley’s character Ray is a “scavenger.”

In the new teaser, the voice of Luke Skywalker is heard, speaking about the character’s past. The new teaser showed fans a first look at how Harrison Ford will appear as Han Solo in the film. The previously unseen footage shows the iconic Han Solo appearing alongside his trusted pal Chewbacca. Fans also got a glimpse of the melted husk of Darth Vader’s mask and got to see several new characters that will be central to the film’s story.
