Co-writer Robert Smigel revealed that the movie was mostly written in the year 2000, but it was delayed after 9/11 due to the terrorist themes in the film.
Adam Sandler's character Zohan was loosely based off of a real-life hairstylist named Nezi Arbib in Solana Beach of San Diego, California. Sandler and the film crew came to the stylist (who was in fact a former Israeli soldier turned stylist) in order for Sandler himself to learn different hairstyling techniques and mannerisms.
Throughout the film, Zohan and other Israeli characters use various Hebrew words and phrases. These include, but are not limited to, Aba
Father; Ima - Mother; B'seder - Okay; and Faygelah - Homosexual.
Sandler's longtime friend and former college roommate, Eric Lamonsoff, who was previously mentioned in both The Wedding Singer (1998) and Click (2006/I), makes his debut film appearance as Hamdi's Passenger.
