Corrected entry: During the dinner, Henry Fonda reads a telegram promoting John Wayne to Rear Admiral Lower half. In Fonda's study he gives Wayne a 2 star pin that Wayne wears for the rest of the movie. A 2 star pin is used for Rear Admiral upper half. Only one star is used for lower half.

Correction: Before 1981 rear admiral upper and lower half, both wore 2 stars so this was correct for World War 2.
