I won't fault your memory.  I watched this and was sure the unit was a 
VIC-20 screen, but I long ago decided otherwise, even before I read the 
IMSAI page about it.

I have the DVD, so I checked it out:

Time index 1:10:56 is where we see the screen. (David has just escaped 
from NORAD on the bus, and then we see a 360 pan around the WOPR)

Screen is 16 characters wide by 16 characters high.

Characters are 8x8

pixel ratio is 1:1, so it is not a VIC screen, which does not have 1:1 ratio

128x128 vacuum flourescent screen.  Characters are bitmapped onto the 
screen, as the character lines do not match up to the 16x16 matrix, and 
adding the longer descender space also does not match up. 

I cut out an 'E' and pasted it alongside the screen capture to count the 
lines and positions to verify.

bitmap available on request.
