Zohan was loosely based on Nezi Arbib, a hairstylist and former Israeli soldier in Solana Beach, California. Arbib taught Adam Sandler and the film crew different hairstyling techniques, while Sandler learned Arbib's mannerisms.
Co-writer Robert Smigel revealed that the script was mostly written in 2000, but was delayed after the 9/11 attacks due to the terrorist themes in the film.
Filmmakers planned on painting fake abs onto Adam Sandler, but Sandler insisted on working out with a trainer to achieve actual toned abs.
Throughout the film, Zohan and other Israeli characters use various Hebrew words and phrases, including: Abba (father), Ema (Mother), B'seder (okay), and Yiddish words, including: faygelah (homosexual), tuches (butt).
Zohan is turned down by several salons in New York City - including Vidal Sassoon's, which is ironic. Sassoon was an elite fighter with the Israeli Haganah during the Arab-Israel war of 1948.
