This is the kind of film that practically encourages ADD, cobbled together out of stray parts from a slew of mostly better movies. North by Northwest (the standard-bearer for this type of escapist fluff), Romancing the Stone, the Mission Impossible flicks, Mr. and Mrs. Smith, Groundhog Day, and even the under-loved Hudson Hawk are just a few of the titles liberally quoted here. The MacGuffin propelling Patrick O’Neill's connect-the-dots script is a super-strength new battery codenamed "The Zephyr." Rogue agent Roy Miller (Tom Cruise) wants to protect the contraption and its dweebish inventor (Paul Dano) from his former agency bosses (the overqualified Viola Davis and Peter Sarsgaard) and a slew of Euro weapons manufacturers. Cameron Diaz is the cutie Roy uses as a mule to help get through airport security then can’t quite seem to shake. You'll forget most of the plot particulars before hitting the parking lot.
