Grace was at first seen wearing a blue sweater and white skirt for a few scenes before changing into a green hoodie and jeans for another set of scenes.
Also seen on set was Monica Lewinsky, who is serving as a producer alongside the real Amanda Knox.
The project is described as being "based on the true story of how Knox was wrongfully convicted for the murder of her roommate Meredith Kercher and her 16-year odyssey to set herself free."
This Emmy-nominated star was originally cast as Knox, but had to drop out of the project reportedly due to "scheduling conflicts."
