Emily and Garrett are in a field and a mud fight ensues. Emily's clothes are very clean until Garrett pulls her to the ground into a mud hole. However at 50:17, during the short clip in which Emily is pulled down, you can clearly see she is already covered in mud. It is as if they practiced the scene but she was not cleaned up prior to the final take.
The name of Emily's business partner is mentioned in the movie as Adam. In the end credits, it is listed as Jodi.
