May already have been reported but in the movie "Sky Captain and the
World of Tomorrow" there are two slide rules. Neither of which I can
identify. But on the DVD version of the movie in chapter 6 (between
29 minutes and 35 minutes).

First slide rule is a circular in the right front/bottom foreground
laying on table between "Dex" and the radio when Dex is calling the
Captain about not shooting the enemy ships. Looks like an old
navigators SR.

Then a few minutes later there is a liner slide rule under Dex's
hands as he works out the transmitters location (Nepal). The SR
sort of looks like a Post/Hemmi 1447 or 1452 but the cursor is too
wide .
