Global box office of the movies the duo has contributed to as writers is over $1 billion.

Diamond and Weissman's partnership is rooted in a friendship that dates back to their high school days together in Philadelphia. The team sold their first spec script, "The Whiz Kid," to 20th Century Fox in 1994. They followed with a series of original ideas for comedies, including their first produced credit in 2000, Universal Pictures' The Family Man, starring Nicolas Cage and Téa Leoni.

A collaboration with Ivan Reitman came next with Diamond and Weissman writing the Dreamworks Pictures sci-fi comedy Evolution. Diamond and Weissman then partnered with Wedding Crashers producer Andrew Panay on a series of feature comedies including Old Dogs, starring John Travolta and Robin Williams, and the romantic comedy When In Rome, starring Kristen Bell and Josh Duhamel.

The partners wrote their first original television script for 20th Television and CBS, resulting in the pilot starring John Leguizamo. More pilot sales followed, for both half-hour comedies and one-hour dramas, at NBC, ABC, FOX, and TBS.

Diamond and Weissman are also the writers of the screenwriting instructional, Bulletproof (MWP, 2019). Their screenplay "Immigrants" won the 2020 screenplay competition at the Ojai Film Festival.

The writing team of Diamond and Weissman is known for concept and character driven stories that add up to more than the sum of their parts.
