Constantin Film and Dark Horse Entertainment are joining forces to bring POLAR to the big screen. Based on the popular Dark Horse Comics graphic novel “Polar: Came from the Cold” by Victor Santos, Constantin Film has pre-emptively purchased the spec, “Polar″ written by Jayson Rothwell. The adrenaline-pumping action-thriller tells the story of Black Kaiser, a master assassin forced out of retirement when he finds himself the target of a motley crew of new generation hitmen. But Kaiser’s gun-blazing and bloody universe is at odds with the doting and protective relationship he has with the child of one of his former marks. Faced with the ultimate battle for survival, Kaiser must choose between saving his life and saving his soul. Constantin Film and Dark Horse Entertainment are currently out to directors with the aim of shooting POLAR in the spring of 2015. Constantin Film’s Robert Kulzer will be producing along with Jeremy Bolt as well as Dark Horse Entertainment’s Mike Richardson and Keith Goldberg. Rothwell is also writing an Untitled Heist Thriller for Thunder Road. He is repped by WME.
