The plot idea is funny but it just needed a script that comedy actors could use and adult audiences appreciate.
Little Nicky (Adam Sandler) is just your average horny, headbanging adolescent with a speech impediment from down south...way down south. Nicky is son of the Prince of Darkness and he lives in Hades (Population: You!), ruled for 10,000 years by his dear old pop, Satan (Harvey Keitel). Nicky has two evil brothers (Rhys Ifans from 'Notting Hill' and Tiny Lister from 'Friday') who think Pop's gone soft and should vacate the throne...even if it means wasting him. So begins a wicked chase that'll take them from the burning underworld to the only place that rivals it for sin, decadence and debauchery - New York City. Out of his depth and hellbent on saving Dad from his unearthly siblings, Nicky is about to encounter what life is like on the other side. Also stars Reese Witherspoon, Patricia Arquette and Rodney Dangerfield.
