Apparently, Resse Witherspoon, the highest paying actress, didn't like Vince Vaughn's laid-back approach to work.
"Vince rolls onto set in the morning looking like he just came in from a night out, while Reese will arrive early looking camera-ready," a San Francisco source told the NyDailynews. "Then Reese tries to force Vince into blocking out each scene and running through their lines as Vince tries to convince her that he's an ad-libber and wants to play around and see where the scene goes."
