This should be under the category of "comedy"!! Many actors played multiple parts in this movie - one in particular: Chloe Rose Bradburn - 1st class passenger, economy class passenger, bartender & even pilot it seems. Oh, she is also listed as the Production Designer! Imagine that? What, they thought no one would notice? It's just cheaper for actors to play multiple roles, right? And the civilian copilot? She was also a pilot for the military aircraft sent to accompany the 747 back to the airport after bomb was discovered. I could not validate this by the credits but the brown eyes & complexion seemed to match. Could not match voice as military pilot had mask on (oxygen). But based on previous observations, why couldn't same person fly multiple aircraft @ the same time? And get me started on stock footage...the civilian aircraft took off as a two engine one, turned into four when in the air, & finally a Boeing 747. The DVD back says there are 800 passegers on board. Depending on its configuration, a 747 can hold between maybe 450 - 550 people, a far cry from 800. In the movie itself, they mention something like 290 on board as I recall. And only two flight attendants!!? Even the airline has gotten cheap! Back to stock footage: F-16 on tarmac for takeoff; fully loaded, bombs, missiles & exterior fuel tank. When the 747 pilot mentioned the F-16s (2) outside the aircraft, they were definitely not F-16s...most likely F/A 18s, may F-14s. No bombs, no missiles, no exterior fuel tanks; so, completely unarmed! Oh, a passenger mentioned he was a retired Army Chief Master Sergeant. That rank is unique to the Air Force. No such rank exists in the Army. And narrative on DVD says "...tons of explosives on board..."? Two carry on bags could not possibly contain anywhere near that weight! States also this DVD is closed captioned? It isn't. Today we use 'subtitles' in various languages. Maybe cover was done before they cut costs by not having CC? Enough said. There were numerous other errors. I enjoyed the movie but the comedy was the best part!
