The Oscar-winning actress - who stars alongside Josh Hutcherson and Liam Hemsworth in 'The Hunger Games: Mockingjay, Part 2' - has revealed she loves taking on dramatically different acting roles, and has claimed that her life has taken on a president-like feel.

She said: "I try to keep working so people can see other characters and other things I can do, instead of taking vacation time, and now I'm ageing like a president.

"I hate waking up without a goal or going to sleep without achieving nothing."

Jennifer - who has reprised the role of Katniss Everdeen for the new movie - also admitted she's resisted the temptation to take time off over the last few months.

The 25-year-old star explained: "I remember there have been a few times where I would have loved time off. But I was very aware of how overwhelming these movies and this character was, and that was a big fear of mine signing on to these movies.

"I want people to be able to lose themselves when they're watching a movie and not see the same character."
