Louis Marinelli and Richie Marinelli are the secondary antagonists of the 1993 Moonbeam Entertainment movie Prehysteria! and the secondary main antagonists of the 1993 Moonbeam Entertainment movie Remote. They are thugs and cousins who were first hired by Rico Sarno to help him reobtain the small dinosaurs that hatched from his eggs and later by Delbert McCoy to help him commit robberies. Although they have each possessed guns before (Richie considering using Delbert's own gun on him) and Louis has possessed a knife, both seem unwilling to ever cause actual harm to anybody who crosses them. They are both louts and act as comedic foils to their darker employers.

In both movies, Louis was portrayed by the late Tony Longo and Richie was portrayed by Stuart Fratkin.
