14. RENÉE ZELLWEGER And JUDY GARLAND

Renée Zellweger transformed into Judy Garland in the 2019 filmJudy. With the iconic voice, stage presence, and tragic vulnerability, Zellweger looked and sounded exactly like theWizard of Ozstar in her later years.
Zellweger trained for months with vocal coaches and performed all singing live. The physical resemblance was uncanny and earned her an Oscar nomination.
