Pushing Tin hails from the lineage of high stress comedies that find humor in occupational head butting. From Broadcast News to the under-appreciated The Paper, filmmakers have fashioned the workplace into a viper pit of egos, testosterone, and crushed emotion. Stress is the key ingredient here, and Pushing Tin, which takes place in an air-traffic control center, has enough of it to put all of its characters on permanent disability. Director Mike Newell succeeds at visualizing a world whose excitement resides mostly on computer screens and in headsets. He assembles a crew of aviation geeks who are truly difficult to like at first, but whose wackiness forms a lovably dysfunctional family. And he doesn’t dumb-down the technical babble that flies breakneck out of their mouths.
