Universal Pictures shared a trailer for Christopher Nolan’s new biopic film, Oppenheimer, featuring Cillian Murphy as theoretical physicist J. Robert Oppenheimer.

Oppenheimer is based on the biography American Prometheus by Kai Bird and Martin J. Sherwin. The film explores how Oppenheimer’s work on the Manhattan Project led to the creation of the atomic bomb. The trailer introduces Murphy as Oppenheimer; Oppenheimer’s wife, Katherine, is played by Emily Blunt, and Matt Damon, Robert Downey Jr., and Florence Pugh also star. Oppenheimer is written, directed and produced by Nolan, in his first film since Tenet was released in September 2020.

Oppenheimer opens in theaters July 21, 2023. Take a look at the teaser trailer – here.
