Shortly after attending Northwestern, at age 19, he sold his first screenplay, Wrestling Ernest Hemingway, adapted from a short story he had written for a creative writing class. Eleven years passed before he tackled his next project, Lawrence Melm, which he wrote and directed. He followed this with The Weather Man (which he also produced) and The Pursuit of Happyness. He wrote, directed, and edited The Promotion, which premiered at South by Southwest in March 2008 and was released by Dimension Films later that year.
His projects include an adaptation of the Chang-Rae Lee novel Aloft for Scott Rudin; Chad Schmidt, about a talented actor with a resemblance to Brad Pitt and The Expanding Mailman with Jack Black.[2]
In 2013, he adapted a James Thurber short story for the film The Secret Life of Walter Mitty, directed by and starring Ben Stiller. In 2015, Conrad developed Patriot for Amazon Studios. Its pilot led to a full series order,[3] and it premiered in its entirety on February 24, 2017.[4] In addition to executive-producing the series, he has also written and directed most of the first season's episodes.[citation needed]
