David Diamond and David Weissman’s partnership is rooted in a 30-year friendship dating to their high school days in Philadelphia. The partners 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 Tea Leoni. Diamond and Weissman next wrote the DreamWorks Pictures sci-fi comedy Evolution, directed and co-produced by Ivan Reitman. In 2005, the team partnered with Wedding Crashers producer Andrew Panay on a series of feature comedies that yielded five consecutive pitch sales and two additional produced credits: the 2009 farce Old Dogs (starring John Travolta and Robin Williams) and the 2010 romantic comedy When In Rome (starring Kristen Bell and Josh Duhamel). 2005 also marked the sale of their first television pitch to 20th Television and CBS; the resulting pilot starred John Leguizamo and Claire Forlani. More pilot sales at NBC, ABC, FOX, and TBS, for both half-hour comedies and one-hour dramas, followed. Together, Diamond and Weissman have conceived and contributed to over a dozen movies yielding a combined box office gross of over a billion dollars worldwide.
