Sally Field has revealed that she had to gain 25 pounds in order to portray her character, Mary Todd Lincoln, in Steven Spielberg's Lincoln.
"It was hard, it was very hard. It wasn't as much fun as you would think. First of all, it was horrifying because I'm of a certain age and I kept thinking, 'If I don't do it right I will drop dead halfway through this and someone else will get the role!'" 66-year-old Field told Jay Leno on The Tonight Show With Jay Leno as quoted by Us Weekly.
Field fought for her role by doing whatever she could to gain the weight. She ate brown rice and drank a high-protein beverage called ProGain that bodybuilders drink.
"Can you imagine to be a woman of a certain age and drinking something twice a day called ProGain? And you put nut butter - you put two huge tablespoons of nut butter in that. And then you eat those bars every two hours, that have, like, 400 calories each," Field explained part of the process as quoted by OnTheRedCarpet.com.
The actress said she never had a fun meal during the process and losing the weight she gained wasn't enjoyable either. It took Field about a year to lose it and even had to have knee surgery as a result of gaining the 25 pounds.
"It took me about six months to gain it, and about a year to lose it. I began to work out like a mad fiend. I had two trainers. I really worked out hard 4 times a week," the actress explained. "I eventually had to have knee surgery. My little frame couldn't hold this amount of weight," Field said as quoted by Us Weekly.
Fans can see Field in Lincoln which will open on November 16.
