Sir Peter Jackson, who directed the 2005 King Kong remake, was caught by surprise at news a prequel to the story is being made.
Studio Legendary reportedly caused a certain amount of confusion among fans at Comic Con in San Diego last weekend with footage from the prequel, called Skull Island, which until then hardly anyone knew existed.
As Forbes tells it, Legendary showed the footage without any explanation and walked away without elaborating on what fans can expect.
The company did later tweet: "Legendary confirmed: feature film based on the famed Skull Island, the cinematic origins of another classic beast King Kong."
When Jackson was asked about the project during an interview with Collider, he replied: "I don't know anything about it. I'm hearing it from you, for the first time. I would look forward to it."
There has been excitement in some quarters that Jackson appeared to want Guillermo del Toro to direct Skull Island.
But in that regard, Jackson may be the victim of a leading question. He was asked by Collider: "What do you thing about Legendary doing another King Kong with Guillermo del Toro?"
"If Guillermo did King Kong, that would be great." Jackson said. "That would be fantastic. I'll be there on the first day, and will help him with anything he needs."
Some commentators have suggested del Toro is in fact far too busy to make Skull Island, while there is also speculation the job of director has been offered to Englishman Joe Cornish, who is in big demand as a result of his low budget sci fi action movie Attack the Block.
