Del Toro: Pacific Rim 2 not prequel
Guillermo del Toro has confirmed Pacific Rim 2 follows Charlie Hunnam and Rinko Kikuchi's characters from the first movie.
A sequel to the director's 2013 sci fi action film - set in the future when specialist pilots power giant robots to battle monsters who have taken over the world - has been in the pipeline before the first movie was even released in cinemas.
Guillermo told BuzzFeed he is now working on a script with Marvel writer Zak Penn.
He said: "I'm working very, very hard with Zak Penn,. We've been working for a few months now in secret. We found a way to twist it around."
The director revealed the current screenplay includes the characters Raleigh Becket and Mako Mori, played by Charlie and Rinko in the first film, and follows on from the events of the first movie.
He added: "Some people were wondering if we were going to do the prequel. I was never interested in doing that first wave of invasion. I'm going for very new, very crazy ideas on the second one, which are very different from the first one - but you will get really great spectacle."
The Mexican filmmaker also revealed he had been working with Travis Beacham, co-writer of the first film, on the sequel, but had now partnered with Zak, as Travis is too busy.
He said: "Now I'm writing with Zak because Travis has become a TV mogul."
But Guillermo admitted Legendary Pictures has not formally agreed to make the sequel.
He said: "I don't have the money, but I'm proceeding like it is happening."
