The Octan Tower is a realm in The LEGO Movie, and Lord Business's lair. As its name suggests, it is a large office tower-like building that is the headquarter of the Octan Corporation. The infinitieth floor of the tower is actually a detachable module and the holding place of the Kragle throughout the film's duration. In the Lego Movie 2 page, it can be seen on the uncredited end titles cards, but name only.
It is first mentioned when Metal Beard muses on a failed attempt to infiltrate the building, when his entire crew was massacred and he alone escaped with his head and organs. He also makes mention of many relics, and the Think Tank. A lot of stuff happens here near the end of the movie. After the attack on Cloud Cuckoo Land, Emmet and his team hatch a plan to Break into the Octan Tower. The first part of the plan involves Emmet and his team building an Octan Delivery space ship to bypass the Laser Gate. Benny and MetalBeard and sneak into the control panel room and try to disable the shield system, but Benny gets frustrated as he keeps failing to get the shield to disable, the computer finding movies, restaurants in Albania, and Where Are My Pants episodes. Wyldstyle and Emmet sneak past the robot builders as they sing the Everything is Awesome song. Wyldstyle tells Emmet her real name (it's Lucy, which Emmet finds a beautiful name), and as they are about to hold hands, Batman comes to help out after leaving Unikitty to stall the robots. Then the scene goes back, Wyldstyle leaves the scene to go do her part. Batman gets his grappling hook ready while Emmet tells Benny to disable the shield, Wyldstyle fakes a call and Bad Cop leaves his position, Wyldstyle takes down the Robot guards and gives the signal. Emmet and Batman get ready and Benny still can't deactivate the shield, then finally MetalBeard tries and disables it just in time. Emmet then barely gets the Piece of Resistance on the Kragle but fails because Bad Cop and the robots find out what they are doing. They are then taken to the think tank and taken hostage. Vitruvius tries to fight back but Lord Business decapitates him with a penny. However Vitruvius comes back as a ghost and tells Emmet that you are special if you believe you can be, knowing it sounds like a cat poster. Lord Business leaves in the top piece of his tower and goes over Bricksburg and the realms. This scene comes before Emmett comes into our world and discovers "The Man Upstairs" and his son Finn.
The Octan Tower is heavily based on the Sears Tower/Willis Tower in Chicago. It consists of five layers, the first being a huge cube, the second being an "L" shape, the third being a more "plus" shape, the forth being a rectangle and the fifth being the exact same as the first, just smaller. There is a detachable module at the top which is shaped like a 2x2 LEGO brick. However, this makes no sense whatsoever as earlier in the film, it was just a standard cube with lights and towers on top, but how it suddenly changes to a cube makes no sense. The tower sits atop a large rock formation which overlooks the sea and the Infinite Abyss of Nothingness. A coyote howls atop the rock. It is protected by the infamous "laser gate".
The inside consists of many rooms, including large robot office rooms, a conference room for Lord/President Business to discuss his plans to Bad Cop and the robots, a relic room where objects such like the Kragle are kept, the Think Tank room, the "Where Are My Pants?" studio, Lord Business' lair room in the module, and many other rooms and hallways. The walls are mostly painted in a white color scheme or in black (like in the Think Tank). The main windows have large red panels around them and most of them overlook the Infinite Abyss of Nothingness. The window in the Think Tank room is broken from when Lord Business "accidentally" kicked the Piece of Resistance out the window. There are two battery-like things for holding the cords for the battery that surround the large screen in the Think Tank and there is a platform in front of the window to hold the 9 volt battery that Emmett breaks to help save the others.
- Despite Metal Beard claiming that it has infinite floors, there is a top.
- It is it's own realm in The Lego Movie Videogame, and it is in Bricksburg in Lego Dimensions.
- To emphasize its scariness, there is a coyote howling at the bottom.
- During production on The LEGO Movie, the Octan Tower originally had a different appearance. It was changed later in production but at the end of the movie when Emmett discovers The Man Upstairs and Finn, the Octan Tower is shown to have it's old design. The reason of this is unknown.
- It is based on the Willis Tower in Chicago.
