''My Big Gay Italian Wedding'' satirizes the controversies surrounding same-sex marriage as well as gay and Italian stereotypes. Anthony Pinnunziato, a gay Italian-American from a large chaotic family, wishes to marry his boyfriend Andrew Polinski in a traditional Italian ceremony. Anthony's overbearing mother won't give her blessing unless Andrew's estranged mother also gives her blessing and the ceremony is performed by a priest. Matters are further complicated by Andrew's ex-boyfriend, intent on breaking up the couple.
