A few comments on historical accuracy (now this is really nitpicking)...
1. The common belief is that Kate horizontal bombers dropped modified 15 in. gun shells as AP bombs, not the big bulbous fat "BOMB" shown in the movie (why does Hollywood insist on dumbing it down).
2. I find it hard to believe that
A. Jimmy Doolittle would endorse a fighter pilot joining Eagle Squadron.
B. That same fighter pilot would be immediately posted to a P-40 squadron at Pearl Harbor upon his return to the United States (I am almost sure that Eagle Squadron pilots were forced to resign US commissions).
C. That a group of fighter pilots would be assigned various crew duties aboard a B-25 Mitchell during the Doolittle Raid.
D. That Adm. Kimmel would nonchalantly discuss war preparations while inspecting troops, and that he and his staff would take credit for Gen. Short's decision to deploy his aircraft in anti-sabotage formations while on the ground. What Navy Aircraft were "parked in rows on the airstrip" PBYs at Ford?
3. As many or more P-36s took to the air during the raid, and from the more centralized Wheeler Airfield as depicted in the film. The P40s were scrambled from Ewa, with it's airship mooring tower (not a "maintenance field).
A trivia note that would help prove however, that things are stranger than fiction. A single American pilot was involved in three of the biggest (or most notable) events of the war. Davy Jones piloted a Doolittle Bomber, was eventually repatriated and flew in the Ploesti Raid, was shot down, captured and participated in the tunnel digging at Sagan (The Great Escape).
By the way, a definitive movie on the Doolittle raid has been made "Thirty Seconds over Tokyo" Although a little jingoistic (consider the production date) the story line is taken from a pilot's actual experiences and was endorsed by Doolittle himself.
I also feel that "Tora, Tora, Tora" was the definitive film on the Pearl Harbor attack itself as it presented both viewpoints and used both US and Japanese historical sources and technical advisors, but that's just my opinion.
