Weitz's father and maternal grandfather were Jewish,[7][8][9][10] whereas his maternal grandmother was Catholic. He was raised in a nonreligious household.[11][12]
Weitz' early career involved many collaborations with his brother.[15][16][17] Some of the work they have done as screenwriters has been both credited and uncredited.[18]
Weitz began his film career as a co-writer on the 1998 animated film Antz. He followed this with work on various sitcoms such as Off Centre and the 1998 revival of the 1977 series Fantasy Island. In 1999, he and Chris directed and produced American Pie, which was written by Adam Herz, and became a major box office success. Weitz returned as executive producer on the film's two theatrical sequels.
Weitz has written and directed the well-received romantic comedy In Good Company and the political satire American Dreamz, which faced mixed reviews. Additional writing credits include the television show Cracking Up.
In 2015, Weitz directed the film, Grandma, which starred Lily Tomlin.[21][22][23] The film premiered at the 2015 Sundance Film Festival on January 30, as the closing night film.[24] The film was Tomlin's first leading role in 27 years, after co-starring with Bette Midler in the comedy film Big Business (1988). It is the second collaboration between Tomlin and Weitz, who previously directed her in his film Admission (2013).[23] The film was released on August 21, 2015, by Sony Pictures Classics.[25]
Weitz had the story idea for many years, but it never fully formed until he met and worked with Tomlin on Admission,[21] saying that "After meeting Lily, the voice and the character really clicked, I had thought about it for years, so I had a lot of it worked out in my head, and then I just went to a coffee shop and wrote it longhand."[23]
Weitz said the film cost under $600,000 to make.[26] It was well received.[27][28][29]
Weitz has a production company with his brother Chris Weitz and producer Andrew Miano called Depth of Field. In March 2016, Weitz and his brother signed a two-year first look deal with Amazon Studios.[30]
A live-action adaptation Michael Moorcock's Elric saga, which his brother Chris said he enjoyed as a child. Weitz's Depth of Field production company was meant to create the films as a potential trilogy for Universal Pictures. In a May 2007 interview with Empire magazine Weitz's brother announced that he had met with Moorcock, who trusted him with the films, and described his wish for Paul to direct the film.[31]

While in college at Wesleyan, Weitz wrote the play Mango Tea, which was performed Off-Broadway.
Weitz has written a number of plays, including Roulette, Privilege, Show People and Trust, all of which have been produced Off-Broadway in New York City.[36]Trust starred Zach Braff, Bobby Cannavale, Sutton Foster, and Ari Graynor, and was directed by Peter DuBois at Second Stage Theatre. It will be produced in Brazil, Germany and Greece in 2013[when?]. Second Stage previously produced Privilege and Show People and produced Lonely, I'm Not, starring Topher Grace and Olivia Thirlby a new comedy by Weitz in 2012. Lonely, I'm Not was a New York Times critics pick.
As a writer, Weitz has discussed semi-jokingly the fact that he avoids the discomfort in his life by turning to the act of writing.[16] He sees a good play structure as being very different from a good film structure, and thinks that it is rare for plays as source material to be easily adapted into film.[17]
