Audio: 4.25/5 (DTS-HD Mono Spanish, DTS-HD Mono English) 4/5 (DTS-HD 5.1 English)

This release comes with three audio options, a DTS-HD mono mix in Spanish, a DTS-HD mono mix in English, and a DTS-HD 5.1 mix in English. There are some trade-offs when comparing the two mono tracks; though ambient sounds and the score sound fuller on the Spanish language audio track, it has some sibilance issues that are not present on the English language track. Of the two English language audio tracks, I preferred the mono over the 5.1, which does a decent job expanding the soundtrack. That said, dialog comes through clearly, and everything sounds balanced on all of the audio tracks. Included are removable English subtitles for the Spanish language track and removable English SDH for the English language tracks.

Summary:

A wealthy man driving a sports car angers a biker gang with Nazi affiliations, triggering a series of violent retaliations with a high body count.

Mad Foxes is a film that keeps things simple; it is first and foremost an exploitation film that takes vulgar elements and moments of carnage and pushes them to their extremes. Its melting pot of genres draws from biker films, revenge films, action films, and nazisploitation, resulting in a truly wild cinema experience unlike anything else. That said, when it comes to the excessive carnage, it goes so far over the top that it looks cartoonish.

Everything starts when the protagonist causes one of the Nazi bikers to crash and die engulfed in flames. The Nazi bikers then assault the protagonist and his girlfriend when they leave a nightclub. Not willing to let what they did go, the protagonist rounds up some of his karate-fighting friends, and they help him retaliate against the Nazi bikers. From there, there are a series of counterattacks leading to more carnage and large body counts building to an inevitable conclusion.

There is only one word to sum up the performances: outlandish. The entire cast fully embraces the destruction and insanity that unfolds. The cast actually has several faces recognizable to Eurocult fans, like Erik Falk, a muscular actor who frequently worked with producer Erwin C. Dietrich, and in the role of the protagonist, José Gras, who many are sure to remember from Hell of the Living Dead. Another character of note is the sports car, which somehow, in all of the mayhem, never gets a scratch.

While exposition is essential for advancing any narrative, in Mad Foxes, it is the moments of carnage that propel the story forward. That said, there is a deliberateness to the pacing that makes things feel much longer than 80 minutes. Instead of cataloging all of the grotesque and brutal ways in which characters die, it is better to let first-time viewers experience it. Something of note about the Nazi Bikers: their swastikas disappear every time they are in a public location. The soundtrack is bookended by a pair of Krokus songs that serve as a perfect introduction and coda to the events that have unfolded. Ultimately, Mad Foxes is a film where anything can happen, making for one hell of a ride.

Mad Foxes gets an exceptional release from Cauldron Films that comes with a strong audio/video presentation and informative extras; highly recommended.

Note about the 4K screenshots: It is not possible to make Dolby Vision or HDR10 screenshots that faithfully match the experience of watching a film in motion on a TV. Instead of not having any screenshots, all of the 4K screenshots are m2ts taken with a MPC-HC player and lossless PNGs.
