Synopsis by Stephen Thomas Erlewine
Splitting Heirs is a dull mistaken identity comedy about a British Duke (Eric Idle) who is switched at birth when his parents accidentally left him behind in a restaurant, picking up the wrong baby by mistake. Idle is raised by Pakistanis and when he discovers his true identity, he begins plotting to kill the American (Rick Moranis) who is the unwitting imposter. His plans go awry, and Idle hires a lawyer (John Cleese) to help him regain his title.
