"A lot of the stuff that I do with Betty is in the eyes. A lot of the feelings that I evoke with her are unspoken, so that's been fun to play with"

January Jones is referring to her function as Betty Draper in the television series Mad Men. She is highlighting the value of her facial expressions and body language in conveying her character's feelings. She is suggesting that a lot of the feelings she conveys as Betty are not clearly stated in the script, but rather are implied through her subtle facial expressions and body movement. This is a fascinating technique to acting, as it requires the star to be very aware of their facial expressions and body language in order to successfully convey the character's feelings. Jones is recommending that this has been a fun difficulty for her to have fun with, as it needs her to be very in tune with her character's emotions and to be able to convey them without using words.
