But then you have sequences like the end of the Jim Carrey romantic comedy Liar Liar, where desperate to catch up with his ex-wife and son who have boarded a plane on their way out of his life, Carrey hijacks an airport stair escalator on the runway and maneuvers it alongside the plane. Due to his trademark reckless but zany efforts, the takeoff is canceled and Jim Carrey gets to convince his son that he's a better dad than Cary Elwes. Everyone lives happily ever after.
Of course, Liar Liar has the excuse of taking place before 9/11, so the cops weren't yet tazing every man, woman and child who reaches for a cell phone in the airport. But then there's Love Actually, which was released in 2003 and actually references 9/11 in its opening sequence, where Liam Neeson encourages his stepson to sneak through airport security at Heathrow without a boarding pass at Christmastime, in order to say goodbye to his school crush. The young scamp runs through the airport, pursued by airport guards, and confesses his love. Afterwards, the guards escort him back to his dad with trademark "kids will be kids" smiles, and then simply let both of them go.
