Reese Witherspoon filmed all of her scenes in four days. Writer and director Paul Thomas Anderson loved working with her so much that he and Joaquin Phoenix, who famously worked with Witherspoon in Johnny & June (2005), began talking with Witherspoon about possibly changing the story so that her character would be around more. However, ultimately the actress convinced the two that it wouldn't be a good idea, something that in retrospect Anderson agrees with.

When Doc goes to see Penny at her office she asks if he will let her depone him. While the use of the word "depone" might seem unusual compared to the more common "depose", this should not be regarded as a mistake. Penny's actual line from the source novel is this: "Would you be willing to depone for me?"
