An American bartender and his prostitute girlfriend go on a road trip through the Mexican underworld to collect a $1 million bounty on the head of a dead gigolo.
Absolutely true -- the movie has the blood of Sam Peckinpah running through its veins (and I'm not referring to its violence but its lifeblood) -- particularly "Bring Me the Head of Alfredo Garcia" and "Pat Garrett and Billy the Kid."
…a little bit like Warren Oates in Bring Me the Head of Alfredo Garcia if Oates' character in that Sam Peckinpah film was an alcoholic USC film professor and a raving, saliva-spewing chauvinist dog."
Take Bill Watterson's classic comic strip Calvin & Hobbes , mix in bits of My Own Private Idaho and Bring Me the Head of Alfredo Garcia, then add some high-quality CGI to let the camera go where it would be physically impossible to fit.
