Robert Downey Jr. clinched the Academy Award for Best Supporting Actor for his portrayal in the highly acclaimed film "Oppenheimer" during this year's awards season.

His victory adds to his previous wins in the same category at the Golden Globes and BAFTA, representing his inaugural Oscar triumph.
