The Catcher Was a Spy is a 2018 American war film directed by Ben Lewin and written by Robert Rodat, based on the book of the same name by Nicholas Dawidoff.

Mark Strong, Sienna Miller, Jeff Daniels, Tom Wilkinson, Giancarlo Giannini, Hiroyuki Sanada, Guy Pearce, and Paul Giamatti also star.

Moe Berg, a 15-year baseball veteran, joins the war effort as a spy to beat Nazi Germany in the race to build the first atomic bomb.

The project was announced on April 26, 2016, with Ben Lewin hired to direct, Robert Rodat tasked with adapting the biography, and Paul Rudd cast as Moe Berg; PalmStar Media would produce.

The website's critical consensus reads, "The Catcher Was a Spy loses sight of the most interesting elements of its fact-based story, dropping the ball and leaving likable lead Paul Rudd stranded.
