Cobra

Cobra is a 1986 American action film directed by George P. Cosmatos and written by Sylvester Stallone, who also starred in the title role. The film co-stars Reni Santoni, Brigitte Nielsen and Andrew Robinson. The film was loosely based on the novel A Running duck by Paula Gosling, which was later filmed under the title Fair Game in 1995. However, Stallone's screenplay was originally conceived from ideas he had during pre-production of Beverly Hills Cop, whose screenplay he heavily revised. He had wanted to make Beverly Hills Cop a less comedic and more action-oriented film, which the studio rejected as being far too expensive. When he left that project, Eddie Murphy was brought in to play the lead role.
