We've had quite a few posts with the words "knight", "day", and "trailer" in the headline ("one, two, three, four, tell me that you love me more"), but I think such gluttony is justified given the upward trend for each new clip.  Knight stars Tom Cruise and Cameron Diaz as “a fugitive couple (on a glamorous and sometimes deadly adventure where nothing and no one – even themselves – are what they seem.”  James Mangold (Walk the Line) directs; the cast also includes Peter Sarsgaard (An Education), Paul Dano (There Will Be Blood), Maggie Grace (Taken), and Marc Blucas (Buffy the Vampire Slayer).

It's hard to parse out what footage is brand new to our eyes, but altogether the new trailer is doing its job.  Over the past several months, Knight and Day has slowly transformed from "potentially silly" to "solid choice" when it comes out on July 2, 2010.

Here's the official synopsis:

An action-comedy centered on a fugitive couple (Cruise and Diaz) on a glamorous and sometimes deadly adventure where nothing and no one – even themselves – are what they seem. Amid shifting alliances and unexpected betrayals, they race across the globe, with their survival ultimately hinging on the battle of truth vs. trust.
