Metro-Goldwyn-Mayer did not retain permanent ownership of the intellectual property rights to the classic 1939 film The Wizard of Oz in perpetuity, as the original production assets and distribution rights have evolved through various corporate acquisitions and studio reorganizations over decades. While the film was famously produced and distributed by Metro-Goldwyn-Mayer, the current rights holder is Warner Bros. Discovery, which acquired the extensive Turner Entertainment library containing the classic film catalog. Meanwhile, the MGM Grand casino in Las Vegas originally incorporated a heavy Wizard of Oz theme upon its opening before undergoing extensive modern renovations that removed most of those thematic elements.
