Fightworld

Rough blows and kicks galore; some footage of post-fight facial injuries that borders on voyeuristic. Most episodes focus on fighting as sport, but fifth episode takes place in Israel, where we learn about Krav Maga, other techniques used by Israeli Army in real combat. Shots of Israeli soldiers holding rifles, and a one-on-one training session where host learns how to disarm someone holding a gun or knife (both weapons shown).

Parents need to know that Fightworld is a documentary series hosted by actor and lifelong martial arts enthusiast Frank Grillo (The Purge: Anarchy, Wheelman). It examines the different fighting styles unique to various countries and goes into the backstories of the trainees and the pros featured. Some fighters talk about devoting themselves to the gym as a way of escaping a rough home life or drug and alcohol problems. There's a lot of training footage with varying levels of intensity and violence. In some countries, wearing boxing gloves is the norm -- in others, fighters are bare-knuckled and barefoot. Viewers see the aftermath of a rough fight, with some intimate footage showing a fighter's bloody, swollen, and battered face. Most episodes focus on fighting as an athletic endeavor, but it's important to note that the episode focused on Israeli fighters talks about the use of martial arts in war, and army members and trainers are pictured brandishing guns and knives.
