Gil's All Fright Diner (2005)

Duke the werewolf and Earl the vampire are just looking for a decent meal when they pull their beaten-up truck into an isolated all-night Texas diner under siege by the undead. Martinez delivers a masterclass in deadpan blue-collar comedy, pairing supernatural exhaustion with zombie swarms, eccentric hillbilly necromancy and eldritch Old Gods. The dialogue crackles with effortless wit, yet the creature-feature carnage remains delightfully messy and genuinely perilous.
