The Force Awakens is officially less than a month away, but we're still getting little bits of information here and there. First up is yet another TV spot — this one shines the spotlight on Oscar Isaac and the X-Wings. You can watch that below.

But more importantly, J.J. Abrams says that Episode VII is all but complete. At a charity event hosted by Stephen Colbert last night, the director said that early on Saturday, "at 2:30 in the morning, we finished the mix of the movie." That means the sound, one of the last pieces to fall into place during production, is completely signed off, and the film is essentially finished. Abrams noted, however: "I left with six very small, but important things that (still) need to be done."

The event was held as an annual fundraiser for the Montclair Film Festival, in New Jersey. Colbert's wife, Evelyn, is vice chairman of the nonprofit's board.

Abrams, of course, didn't let loose any new details about the film — Disney is being very careful to keep spoilers under wraps until release — but he did talk a bit about production. Colbert, a proud nerd, teased Abrams about the director's signature (and over-the-top) lens flares, prompting this response: "As you’ll see, I’ve allowed lens flares to take a backseat." He added that any time he felt compelled to add in gratuitous lens flares, Roger Guyett, of visual effects firm Industrial Light & Magic, would rein him in. "Every time there could be a flare, Roger would tell me, ‘These are not the flares you are looking for.'"

"These are not the [lens] flares you are looking for."

That said, the film won't be entirely devoid of the visual flourish — even Colbert noted that you can make out a few in some of the trailers. Abrams has previously apologized for his overuse of the effect; back in 2013, he said, "admitting you're an addict is the first step towards recovery."

The perfectionist director also provided this lengthy (and telling) response to a fan's question asking if he was glad to be finished with the high-stakes project:

The truth is working on this movie for nearly three years, it has been like living with the greatest roommate in history for too long. It’s time for him to get his own place. It’s been great and I can’t tell you how much I want him to get out into the world and meet other people because we know each other really well. But really, Star Wars is bigger than all of us. So I’m thrilled beyond words (to be involved) and terrified more than I can say.

Star Wars: The Force Awakens hits theaters on December 17th.
