The Eden Project is the world's largest greenhouse, housing thousand of different bugs, wildlife and plants in its huge domed structures called "biomes".
The largest is the humid tropics biome which is tall enough to house the Tower of London!
The crew start filming scenes for the 20th Bond film at the project on Saturday in three 12-hour shoot.
007's arch-rival Gustav Graves in the film, played by Toby Stephens, will be involved in most of the scenes there.
The crew have also been spotted filming in Holywell Bay near Newquay. There they've turned the golden Cornish sands into a North Korean battlefield for the film.
The new Bond flick's due out in November.
