Isaac Florentine (Hebrew: יצחק פלורנטין; born 28 July 1958) is an Israeli film director. He is best known for his martial arts and action genre films, namely Undisputed II: Last Man Standing (2006), Undisputed III: Redemption (2010), Ninja (2009), Ninja: Shadow of a Tear (2013) and Close Range (2015) and for launching the career of British actor Scott Adkins. Florentine completed his degree in Film & Television from Tel Aviv University.^[1]

Florentine regularly visited local cinemas throughout his childhood in Israel, citing Sergio Leone and Bruce Lee as his biggest idols and subsequent film influences.^[2] As a young man he completed mandatory service in the Israeli Army for three years before studying Film & Television at Tel Aviv University. He also trained in martial arts since his childhood, learning judo and karate from the styles Kyokushin, Shito-ryu and Goju-Kai, and started teaching karate in 1978 before opening his own school in 1979, where he would also train regularly to this day.^[3] While studying at University he completed his first short film, Farewell Terminator (1987), which notably won seven awards at Mograbee Film Festival.^[4]

In 1988 he moved to America with his family to pursue a career in film. His first break came from meeting producers Ronnie Hadar and Jonathan Tzachor who invited him to join the production team behind TV series Mighty Morphin' Power Rangers as a stunt coordinator and second unit director.^[5] After seeing his first short film, Cannon Films' Menahem Golan also offered Florentine the chance to direct his first feature film, Desert Kickboxer (1992).^[6]

Florentine is positive of his time on Power Rangers where he honed many skills and filmmaking techniques. However, he would not embrace his now recognised directing style, shooting with minimal, clean edits in the mould of his other idols Buster Keaton and Charlie Chaplin, until his third feature film, High Voltage (1997).

As a next major step in his work, he cast young British actor Scott Adkins in a supporting role for Special Forces (2003), having received his demo tape, and it would mark the first of many collaborations, including producing, directing and even second unit directing, launching Adkins' career.^[7]

Florentine also directed the documentary The Life and Legend of Bob Wall (2003) and second unit directed The Legend of Hercules (2014).
