Renee Zellweger says she looked up to screen icon Judy Garland as a child.
The actor's titular performance in the biopic "Judy" is garnering major Oscar buzz for best actress.
"Nobody was prettier, nobody sang prettier... the adventures she had, (she was) my childhood hero, absolutely," Zellweger told Variety.
The actor transformed into the legendary actor not just physically but also vocally.
Opening about how she mastered Garland's voice, she said, "Instead of thinking about the inimitable, extraordinary quality of her voice, I just looked at it methodically and broke it down stylistically and tried to approach it that way to learn this style of singing to, like, just become familiar with the characteristics of her style that are definitively, uniquely Judy and go from there."
