This was hard to pierce because Darin is an Argentinian star - and Conroy is an American voice actor.
Kevin Conroy was in Batman: Mask of the Phantasm with Mark Hamill
who was in Star Wars with James Earl Jones
who was in Clear and Present Danger with Willem Dafoe
who was in Paris, je t'aime with Hippolyte Girardot
who was in Jump Tomorrow with Natalia Verbeke
who was in El Hijo de la Novia with Ricardo Darin
Barely made it. Someone else take it - my brain hurts.
