I want to know the answer to the following question:
Who studied Beyoncé during live concerts for research for a film's music role?
All the background I'm provided with is that "American indie rock band White Rabbits also cited her an inspiration for their third album Milk Famous (2012), friend Gwyneth Paltrow studied Beyoncé at her live concerts while learning to become a musical performer for the 2010 film Country Strong.". Is that enough to answer the question?
