Besides Playboy Playmate of the Year 2012 Jaclyn Swedberg, none of the actresses who appear nude in Muck (2015) had previously done so on film.
Muck (2015) is full of old-school practical effects, and trumpets "No CGI" as a staple of the film's marketing, as Steve Wolsh has expressed "no desire to direct computers." In fact, he designed many of the stunts and stunt props himself, such as the trick axes and pitchfork blood effects, which were powered by fire extinguishers full of blood.
Playboy Playmates of the Year 2013, Raquel Pomplun, and 2014, Kennedy Summers, have been cast in the Muck (2015) prequel, Offed: Muck prequel (2015).
Kane Hodder's makeup took 6 hours to complete each day, and incorporates natural scarring from burns he suffered earlier in his career when he worked as a stunt man. Muck (2015) is the first film in which Hodder appears shirtless.
The surround sound for Muck (2015) was mixed at Universal Studios Sound Facilities on the weekends, though Muck was frequently bumped off the schedule while Universal was finishing Fast & Furious 6 (2013) at the time. The head of the sound department was so impressed after seeing Muck that he mixed it personally, free of charge.
