"Everyone we're interviewing, we are basically asking them to ask the next person a question," the magazine told Hathaway, who was then assigned to pose a question for Titanic star Kate Winslet.
"Um... I can't talk to her, I'm so shy!" Hathaway says in the clip, eventually regaining composure and asking, "Um... Kate Winslet. What is your favorite breakfast? That is my question."
The British actress, 38, responded in another clip saying Hathaway was "so sweet" and revealing that: "My favorite breakfast probably in the whole wide world, real treaty favorite breakfast, is eggs benedict."
The chain letter continues with questions and answers from Theron, Andy Serkis and Chris Pratt.
The magazine's attempt to create "the world's most audacious video chain letter," has an almost 7-minute duration and took nearly five months to complete.
