Disney Studios chairman Alan Horn teased to fans during a Tribeca Film Festival panel the film is close to locking down their cast.

During an interview with Bloomberg TV, Horn revealed the film's cast is "almost complete" and would be revealed soon.

"We're not prepared to announce it yet, but we will be very shortly," Horn said.

Horn confirmed the movie has already begun production, but the actors aren't on set. The Disney executive explained the production needed extra time to give their sets the "Star Warsian" feel before filming can begin.

The "Star Wars Episode 7" production is expected to bring in a big paycheck for Disney, who is willing to dish out the cash. Horn confirmed to Bloomberg the production doesn't have a budget, but expenses are adding up.

"These large, tentpole kinds of movies, on the expensive side, are in the neighborhood of $175-200 million, that kind of a number," Horn said."...We need to give the audience, essentially, a full meal in return for their affection and devotion and love for these properties."

Screen Crush recently published a photo of one of the alleged sets based in Abu Dhabi. The publication claims the image shows an AT-AT piece, a "four-legged walker introduced in 'The Empire Strikes Back'."

"What will likely happen is that the feet/legs of the AT-ATs will be built practically on set while CGI is used to create the rest of the walker (or, perhaps this is being used for a close-up that takes place at ground level and a wide shot isn't needed), " Screen Crush reports.

Thought the production has yet to confirm their lead actors, "Star Wars" franchise stars Carrie Fisher, Harrison Ford and Mark Hamill are expected to return. "Star Wars Episode 7" will be released to theaters on December 18, 2015.
