Don Eladio himself represents an equally eye-popping connection between Scarface and Breaking Bad. The character first appeared during a flashback sequence in the eighth episode of season 4, "Hermanos." Two episodes later, he meets an unpleasant fate at the hands of Fring, who enacts a scheme in which Eladio and all of his top men are poisoned (Fring, having consumed the same poison in order to gain Eladio's trust, barely escapes with his life).

Even the most sharp-eyed viewers could be forgiven for failing to notice that Eladio is portrayed by Steven Bauer — the very same actor who played Tony Montana's doomed best friend and partner in crime, Manny Ray, in Scarface. Bauer is much older and looks quite a bit different in his Breaking Bad appearance — but he's still as skilled an actor as ever. He imbues Don Eladio with a quiet authority and surface chumminess that belie his deadly, predatory nature.

Pretty crazy, right? Well, hold on to your butts, because as it turns out, the Scarface-Breaking Bad connection has even extended to Breaking Bad's just-as-awesome spin-off prequel series, Better Call Saul. In that show's first season, we caught a glimpse of the home life of Hector's psychotic nephew Tuco Salamanca, who served as a Big Bad for a stretch of episodes during Breaking Bad's first and second seasons. Tuco is seen living with his elderly grandmother — who is portrayed by Miriam Colon, the same actress who briefly appeared in Scarface as Tony Montana's mother. 

At this point, Pacino himself could cameo on Better Call Saul's upcoming sixth and final season, and we wouldn't be too surprised.
