Continuing work on her latest project, Cameron Diaz was spotted having a blast on the set of "Knight and Day" in Salzburg, Austria yesterday (November 19).

The "Charlie's Angels" hottie looked to be in good spirits as she joked with the cast and crew in between scenes at Festspielhaus, also taking a few moments to wave to fans who were watching nearby.

Up to this point, Cameron has been filming in Boston, Massachusetts and the Salzburg shoot is expected to last for about a week. Earlier this month, hundreds of local Austrians tried out for roles as extras.

Miss Diaz stars alongside Tom Cruise in the new action comedy flick, under the direction of James Mangold. "Knight and Day" is scheduled for a Summer 2010 release.
