Details about production of Star Wars: The Force Awakens may have been some of the most heavily-guarded secrets in all of Hollywood prior to release, but now that the film has been seen by millions around the world, all those details can finally be exposed.

That looks to be the goal of Secrets of the Force Awakens, the name of the behind-the-scenes documentary that will be shipping with DVD and Blu-ray copies of The Force Awakens next month. ABC has now released a sneak peek trailer for the documentary that should give fans a better idea of what to expect from the special features for the upcoming home release, including screen tests, deleted scenes and more.

Interviews with the cast in the trailer below reveal what was going through each actor's mind throughout filming the movie, and fans will even get a look at the screen tests that landed each actor their roles. John Boyega's is featured in the trailer, in which he recites some of his early lines from the film as his character attempts to flee the First Order by stealing a Tie Fighter.

The trailer also explains where exactly Captain Phasma's name originated from. According to J.J. Abrams, the chrome outfit of the stormtrooper commander reminded the director of the chrome ball in the 1979 film Phantasm.

"I always loved the design of that, so when we were looking at this, I thought Phantasm and Phasma," Abrams says in the trailer.

Adam Driver, who plays the new big bad villain Kylo Ren, also chimes in to talk about how putting on his elaborate costume helped get him into character. Harrison Ford even appears in the trailer, offering some insight into the film's climactic moments in which Kylo Ren murders fan-favorite Han Solo.

"I wanted Han Solo to be able to lend some significant emotional weight to the story," Ford says in the trailer.

Looks like the documentary will dive into it all, and fans don't have to wait too much longer to see it. Star Wars: The Force Awakens arrives on DVD and Blu-ray April 5.
