Lawrence recounts how she had to pee into a bucket on set while wearing a wedding dress and also said that the hardest and most emotional scene was the one where Katniss couldn't say goodbye to her family.

The actors and director spent the day touring Google, Twitter, Yahoo and Facebook offices as part of the movies' "#GlobalFanDay," answering questions from each company's audience.

In Catching Fire, victors of past Hunger Games will compete in the 75th Hunger Games, also known as the third Quarter Quell. It's a gruesome tradition that pits previous winners against each other every 25 years.

Catching Fire arrives in theaters on Nov. 22.
