The Film: Total Recall (1990)

The Traitor: Benny (Mel Johnson Jr)

Who Do They Betray? Douglas Quaid (Arnold Schwarzenegger) and Melina (Rachel Ticotin).

Oh, Benny, Benny, Benny. A jive-talking, fast-living mutant cabbie who claims to be a member of the Mars resistance, he initially offers to help out Quaid on his mission to stop Cohagan (Ronny Cox) from killing the rebels by cutting off their air.

Turns out he was working with Cohagen all along! Bastard!

Comeuppance? After the nasty Benny chases Quaid and Melina with a massive drilling rig through the tunnels of the planet, he makes a fatal mistake by thinking that Quaid's handheld drill can't hurt him.

But Quaid drills through one of the machine's oil lines, knocking it out, then shoves the bit into the cabin, spearing Benny with the classic line, "Screw you!"



The Film: The Godfather Part II (1974)

The Traitor: Fredo Corleone (John Cazale)

Who Do They Betray? Michael Corleone (Al Pacino)

Clearly pissed at being treated as the muppet of the Corleone family, Fredo makes some very bad choices when he decides to betray Michael and switch his allegiance to gangster Hyman Roth.

Sadly, Fredo can't hold his drink and spills crucial secrets that let Mike know he's the big traitor in the clan.

When Michael confronts him, Fredo chooses to flee - bad move.

Comeuppance? Michael signals to top aide Al Neri that Fredo's protection from harm - requested by their mother - is now over.

Our last sight of the man is while he's fishing on Lake Tahoe with Neri, who puts a bullet in his brain as Michael quietly watches from his house on the shore.

Talk about sleeping with the fishes...
