There are alot of similarities between this film and the original:
They both take place in a High School (Miami, Florida for The Substitute and Brooklyn, New York for this film)
A teacher is either attacked or murdered (Jane played by Diane Venora in The Substitute and Randall, Lt. Karl Tomasson's (played by Treat Williams) brother in this film) by a gang or thugs.
Shale (played by Tom Berenger) and Karl Tomasson (played by Treat Williams) both go undercover as Substitute teachers to uncover the attackers of their loved ones.
In the original film, the High School was used a Drug Storage and Distribution Facility and in this film, the school auto mechanics shop is being used a "chop shop" for stolen cars.
The gangs have similar tag names. "The K.O.D" (Kings of Destruction) in the first film and "The Brotherhood" in this film.
The character of Joey 6 appears in both films played by two different actors (Raymond Cruz in the first film and Angel David in this one)
The main villain in each film is either a former law enforcement official or a military soldier. Ernie Hudson was a former cop turned principal/drug trafficker in the first film and B.D. Wong was a former Lieutenant in the Army which is how he found out Treat Williams' true identity later in the film.
Both Shale and Karl have a love interest in each film. Diane Venora for the first film and Michael Michele in this film.
Joey 6 performing surveillance in this film following the gang members of The Brotherhood as in the original as he was tailing Juan Lockas character played by Marc Anthony using the same or similar equipment.
The truck Joey 6 is driving in the film is almost the same one that Tom Berenger uses in the original film.
Both Shale and Karl teach a class of unruly, disruptive and gang associated students in each film.
Both Shale and Karl each have a tactical military style fight demonstration in the classroom against unruly students trying to attack them. Shale is confronted by two students in the original with one holding an ice pick using a Vietnam allegory referencing "In Vietnam you had to have eyes in the back of your head" and Karl is confronted by Mase (Eugene Byrd) who is carrying a butterfly knife referencing the "absence of compromise" in his defense after throwing the boombox out of the window. They both easily obtain their weapons by utilizing a similar martial arts move nearly breaking their arms or fingers.
While undercover Shale and Karl Tomasson each acquire some unexpected help from either another teacher or a janitor. Shale (Tom Berenger's) character had the help of Glenn Plummer in the original film and in this film, Treat Williams acquires the help of Johnny Bartee, the school's janitor and a former soldier, who happens to be a Tunnel Rat.
The climactic fight between members of The Brotherhood and Tomasson, Joey 6 and Johnny Bartee take place inside the high school at night just like the finale in The Substitute where Shale and his crew took out Rolle, Johnny Glades, John Janus and their crew.
In both films, Joey 6 is wounded during the climactic gun fights inside the High School.
The climatic confrontation between Tomasson and Drummond is a hand to hand combat fight only slightly different than the one between Shale and Rolle at the end of the original film both in terms of the location, the utilization of various garage tools and the end result of the fight. See more
