Over her padded suit, the Academy Award winner wore a housedress that featured a pattern of purple and yellow flowers and green leaves as well as a lavender zip-up bodice.

Renee's face was heavily made up with facial prosthestics added to give the star deeper wrinkles, a fuller face and a wider nose so that she more closely resembled the murderess.

The Texas native's cropped blonde hair was styled into an unkempt bob and she sported fuzzy pink slippers.  

Zellweger filmed scenes in which she was seen standing outside of a house surrounded by the production crew.
