For those who have never been to Ikea, they have a bit of a reputation for having furniture that is tricky to assemble with confusing directions, missing parts, extra parts, and an apparent chaotic neutral alignment.
One of the funniest things I read online was a guy who said, while putting together Ikea furniture, he listens to the theme from MacGyver.
Ikea furniture features prominently in the Deadpool movie, with a gag involving its assembly just past the middle of the film and then Wade goes on an epic flipout just before the climax. In the back of my mind, I wondered what it took to get clearance from Ikea to put that in the movie. After all, the Thomas The Tank Engine appearance in Ant Man came with several pages of instructions from the rights holders about what the filmmakers could and could not do with the character during the fight scene.
Turns out? Not that much.
Ikea had only one stipulation for using them for cheap jokes in the movie -- Rhett Reese, one of the screenwriters, told Digital Spy that, "The one thing we weren't allowed to do is make names up." And he thought the exact same thing anyone reading that thought -- "There was a wealth of real-life furniture to choose from, so it wasn't a problem."
I have a newfound respect for Ikea. Not enough to keep from swearing when I put their shit together, but still respect.
