The writer-director says — spoiler alert! — that while trailers for “Star Wars: The Force Awakens” feature footage and dialogue that didn’t ultimately end up in the final cut of the movie, the discrepancies weren’t meant to throw anyone off.
“It’s a fairly common occurrence when you’re working on a movie, and it’s a year or six months out,” said Abrams. “We were still editing, refining and adjusting the film. That evolution process is something that’s hard to predict.”
