The MacGuffin
Giving the characters an object, secret or goal that everyone chases. What it actually is barely matters, because its job is to set the characters against each other.
How this film uses it
The anti-missile equations of Professor Lindt are what everyone wants. The film never explains the math, and the equations matter only because both sides want them. Armstrong goads Lindt into revealing them by making Lindt think he has made mathematical mistakes.
Where to see it
The classroom duel. Armstrong angers Lindt over what Lindt thinks are mathematical errors, and Lindt gives away his equations.
