Rebel Wilson spoke about working long hours, but maintaining a healthy lifestyle.
The 29-year-old said: "You need to be physically strong for this job. I like to have the stamina to work 16 hours a day. I may eat a lot, but I am very healthy.
"It's becoming important for me. I saw a lot of girls were beginning to notice what I wear and I feel a kind of responsibility, because there aren't any women in Hollywood my size and age.”

The Hollywood actress confessed to having "zero fashion sense", but since becoming more famous she has started to take more care in her appearance.
Career wise
Rebel explained about the two job types she was getting herself into, and said: "How I see it is, I do two types of job: dream jobs like female-driven comedies and the other job which is basically the boys' club.
"I have done three big movies with men – these are talented, strong-minded males, but you have to find a way to work that system.
"You aren't being paid much and you start at a disadvantage with the script. Usually, you don't have any cool jokes and you're there to support the male actor.
"Those male roles are 90% written and formed by the time the filming starts but the female roles are only 20% there. It's unfair, but I love being funny so I improve the role, work with the limited parameters and opportunities and maximise them.
"If you are a woman in that situation you work harder, sharpen your skills more; you need to be two or three times as good as the guys. I just go in there and try and crush it."
