I wasn't around when the 70's Kong films came out, could someone tell me was there any time that Jessica Lang or Jeff Bridges were going to be in this?
It seems strange both these people tried to help Kong in the first one but afterwards just arn't around?
Before the 1976 Kong film came out, producer Dino De Laurentiis had already claimed that a sequel, King Kong in Africa, was going to be made in the near future. However, his version of Kong underperformed at the box office and so the sequel was never made. However, the Dino De Laurentiis company fell on hard times in the 80s and needed a film to try and earn back some money. That film would be King Kong Lives, a film made with seemingly a fraction of the budget of the original.
Dino De Laurentiis was no longer a major player in Hollywood and both Lange and Bridges had gone on to become bigger stars. There was no chance that they would have been convinced to appear in the sequel. Still, it may have been beneficial to have a cameo appearance by someone else adopting the roles. While I couldn't imagine Jessica Lange returning to her role of Dwan or Bridges to his role of Jack Prescott, I couldn't imagine the characters themselves having no interest in Kong after he's revived some ten years later.
