Dear Mr. del Toro:
Can I just say, congratulations on Pacific Rim? I know that in the U.S. the opening numbers were a little shaky (damn you, Grown Ups 2. Damn you straight to hell) but things look really promising internationally, the merchandising opportunities are sound (LET ME BUY ALL THE THINGS!) and you're building credibility with people who have the means to fund your next films.
All that aside, though, you and I know that only matters in the sense that it allows you to continue making visually stunning films. So here's my proposal:
Do a Reverse Trilogy.
Do it. You know you want to. Build on the very probable success and very real populatrity of Pacific Rim to make a Reverse Trilogy. You ended your excellent film with a pretty solid finale. The Breach has collapsed, and whoever The Masters were, their cloning facility is severely damaged - perhaps beyond repair.
Anything further without a really solid, plausible reason to pick up where you left off would be a waste of the world that you've so deftly created. So why not move backward instead of forward?
Pacific Rim II
Set in the middle of the Kaiju wars. The Jaeger program is in its prime (Mark I - III are out, and work is being done to develop the Mark IV [Crimson Typhoon]). The Kaiju rising from The Breach are consistently Category 1 & 2, with the impending arrival of the first-ever Category 3. Stacker Pentecost is wielding maximum influence on the leaders of the governments that make up the Pan Pacific Defense Corps. We see Gipsy Danger run her mission with Herc Hansen, as was mentioned in the first Pacific Rim movie.
There is a not-insignificant sub-plot involving Cherno Alpha and Sasha and Aleksis. Perhaps this is during the six-year period in which they're holding the line against the Kaiju at their post on the Russian coastline.
There is a team effort to defeat the first Category 3 Kaiju, with Crimson Typhoon and the Wei triplets revolutionizing the Jaeger strategy with their three-person drift and using Thundercloud attack to deadly effect. The film closes on this historic win (or maybe even on Raleigh and Yancy's tragic battle with Knifehead, which marked the beginning of the end for the Jaeger program).
Pacific Rim III
The Golden Age of the Mark I and Mark II Jaegers, but a rough time for their pilots, as they learn to win against the Category 1 and Category 2 Kaiju. There is MORE Cherno Alpha and there is Coyote Tango, piloted by Stacker Pentecost and Tamsin Sevier. This film would cover the inception and development of the Jaeger program - before the safety measures were in place to protect Jaeger pilots from radiation.
Remember that the only Mark I pilots we meet in Pacific Rim are Pentecost and the Kaidonovskys. The film closes on the Onibaba Incident, in which Pentecost loses his co-pilot and goes on to defeat Onibaba while piloting Coyote Tango alone - saving Mako Mori in the process.
So how about it, Guillermo? Are you willing to add me to your creative team? If not, are you willing to at least steal this idea and take credit for it? Because seriously, just seeing these films as I envision them will be payment enough.
Although the money would always be welcome, too.
