Paul Walker -- Laughing & Smiling ... Minutes Before Fatal Crash [PHOTOS]

Paul Walker was in a great mood just moments before his fatal Porsche accident -- laughing and smiling in the passenger seat of the car that killed him.

The photos were shot as Paul and driver Roger Rodas were leaving the Santa Clarita charity car show that Walker had organized.

It's a jarring look into the final moments of the actor's life -- especially the juxtaposition of the gleaming red sports car ... and the fiery wreck it became just minutes later.
