Jennifer Lawrence: Sewer scenes sucked

Jennifer Lawrence and her Hunger Games castmates couldn't stop complaining while filming tricky parts in the latest film.

The actress teams up with Liam Hemsworth and Josh Hutcherson for one final time in Mockingjay - Part 2. It's been deemed one of the scariest in the series, with an underground sewer setting taking audiences by surprise. Not only is it one of the hardest scenes to watch, Jennifer and co also found it tough to film.

"It was hard," she candidly told Britain's Heat magazine. "It was rough. Poor Liam couldn't stand up straight for three weeks. We were exhausted, because when we did the fight sequence in the sewer, all of our gear and our costumes were completely waterlogged, so it was an extra 20 pounds. To me, it felt like an extra 2,000 pounds. We were all just complaining."

Jennifer and her co-stars have become very close since the first film screened in 2012 and they all message each other in a special WhatsApp group. It's also been refreshing to have friends who can help her deal with fame.

Now that everything has come to an end, it's still not quite sunk in for Jennifer.

"The job is so full-on," she admitted. "If you are working, it's 13-16 hours every single day and in a strange city where you don't know anybody. Then you wrap and you've got (all this) time off. It's hard to find a balance because you go from being overworked and all, 'Oh my God, I need time off, I'm so exhausted. My body!' Then you get time off and your mind is going crazy. I hate waking up without a goal and going to sleep without achieving anything."

The Hunger Games: Mockingjay - Part 2 hit cinemas last week (beg16Nov15).
