In June Radio 1 Breakfast Show host Nick Grimshaw got a peak at the making of the latest Bond movie, Spectre, at Pinewood Studios near London.
We've been sworn to secrecy on much of what he saw, until now.
For example, Grimmy got to watch the opening sequence, which included a stunt with Bond himself, Daniel Craig.
More than 600 people worked on the movie and Grimmy's chat with producers Michael Wilson and Barbara Broccoli was even interrupted by gun fire.

"We have the most spectacular crew. All of them feel a tremendous loyalty to the franchise and they want to better themselves," says Broccoli.
"Not to mention at the helm, Sam Mendes, who wants to make this even better than Skyfall.
The Spectre plot involves "a cryptic message from Bond's past"
"And our gorgeous Daniel Craig, who is at the heart and soul of this whole franchise and is leading the charge, wants to make the best film possible," she added.
We met the gadget man
Chris Corbould says his career actually began when he was 16, just after his exams and he was asked to go and work on the set of a film called Tommy.
He said: "I was caught by the bug, never went back to school and started learning engineering."
His team do all the gadgets on all the Bond cars. Remember when the tube crashed on Skyfall? Yep, he did that too.
Corbould showed us a helicopter, which was being winched up on wires and launched across the set.

"For various reasons, sometimes we shoot scenes out of sequence.
"We've actually crashed the helicopter and now they are going back to a scene prior to the helicopter crashing."
And he admitted it's not always easy to live up to the script.
"I have to go away and I get all my guys in a huddle and we talk about it and nine times out of 10, we go for it.
"The Bond franchise has a history of doing things for real, so, hence we crash it for real."
We talked to the man 'trying to top Skyfall'
Dennis Gassner says he's "the architect of the film" and his job is to create all the environments for the actors.
"The question that I have generally is 'what's the story and how do we go about doing it?' And Sam would say something like 'can you find me something hot and cold'?
Sam Mendes said he took on Spectre for "the second part of a crucial story of Bond's childhood"
"It's like a piece of music: it has to flow, it has to feel right, it has to have its crescendos, its false crescendos, its movements.
Gassner has a room on set where every scene is planned out across a wall with pictures - but of course Grimmy wasn't allowed in there.
He says his job is like puzzle making, to find the best "pieces" to present to fans.
"We're really trying to top Skyfall, that's what we're really doing and that was really the basics of the job. That's like saying 'how do we top ourselves' and is also probably the hardest thing we could do."
We met the woman behind the suits
Jany Temime says day one was "M's office in Pinewood, that's how we started." She also revealed she was nervous because it was Daniel's first suit.
"It was a new suit, it was a new shape. But boy, after the first day, it's every day," she joked.

She walked Grimmy through Daniel Craig's dressing room, which included the clothes for his stunt doubles.
And she revealed that sometimes the star says he won't wear certain costumes.
"Of course he does. Every actor does...
"And then you say 'why not?' and then you say 'OK', and then you give him what he wants, because he has to play the part.
"Daniel is extremely sexy, beautiful, charming, so it's a pleasure to make him look good and he looks good. He looks even better without the suit," she laughed.
She says she makes the same outfit in different ways, including thing like reinforcements, for the action scenes.
Sam Mendes said he took on Spectre for "the second part of a crucial story of Bond's childhood"
She says if you want to get into the industry "you have to be completely mad to work 80 hours a week and you have to love film".
We talked to the stunt boss
Gary Powell says his job "is having lots of fun" and "coming up with a lot of the action, training the actors and getting the right stunt team in".
It's his seventh Bond and he says the hardest bit of his job is being sent away from his family for months on end.
This is Grimmy getting to watch a little bit of Spectre being filmed
This time he says the best stunt was with the cars, the Aston Martin DB10 and Jaguar CX75.
There was half of an Aston Martin on set for interior shots, Gary explained. He revealed they use the Top Gear track for tests and Daniel Craig can get around that "really quick".
"We had an amazing time with two cars, basically built from the ground up, for us to do what we were doing in them.
"So it was a real privilege to be in something that only a real handful of people have driven."
And is there a lot of pressure to make sure that stunt looks good? Gary said "just a little bit".
Spectre is released on 26 October
