Texas's movie is...

Giant

As the saying goes, everything's bigger in Texas, from its land mass to its imprint on the nation's imagination. So if you're only picking one movie to exemplify the Lone Star State, it better be huge, and Giant fits the bill on several counts. George Stevens' tale of two generations of ambitious Texans is, at 201 minutes, epic in scope, and features several Hollywood titans (Elizabeth Taylor, Rock Hudson, and, in his last role, James Dean, to name just a few). It also captures the beauty of the state's vast wide-open spaces, as well as the entrepreneurial resourcefulness of its people (the Benedict family graduates from ranching to oil riches), showing how the West was won - or at least tamed. Obviously, a state this massive can't be embodied by a single film, and plenty of other movies have explored everything from Texas' pioneer spirit (Rio Bravo) to its changing demographics (Lone Star) to its unique citizenry (Slacker) and customs (Friday Night Lights).
