Ana Ortiz originally auditioned for the role of Betty. She made an effort to change her appearance for the character, but she knew she was not right for the part. She said, "I was super plain. I just put on some glasses and kept my hair kind of flat and layered on the clothing. My objective was mainly to go in there and give a really good audition because I was so excited about the project." Ortiz was asked to play Betty's older sister Hilda instead.
