==Explanation==
String theory hypothesizes that there are many more than 3 dimensions, it's just that we can't see the rest because they're "rolled up." A common metaphor is an ant on a tightrope--it has two degrees of freedom, one along the rope and one around it, but from far away we can only see one.

So Black Hat Guy released his 2D movie about string theory in "3D", and claimed that the third dimension was there--just too small to see.

==Transcript==
Person #1: Your movie was a ripoff.
Person #2: It wasn't 3D at all!
Black hat guy: Was too.
Black hat guy: It's just that the third dimension is tightly rolled up and too small to observe at normal energies.
