Aliens! Can we get some space aliens into this? I really liked those aliens in the last Indiana Jones movie.
But wait -- having Aslan appear as an albatross (who actually first looks like a cross in the sky to Lucy) is too religious. Let's say they escape the aliens by a deep hypnosis which convinces them the alien hallucinations aren't real, so they aren't frightened, and then they rescue Rhoop and everyone trapped there, and send the aliens packing. Reepicheep battles a robot cat.
Cool! They can rename the movie End of the World Trek, or Eastern Ocean Trek and Reep can be better than a robot. Sort of an android like Data in Star Trek. They can start the movie with Douglas Gresham announcing "to blodly go where no Narnian has gone before."Robot Reepicheep! Very good. That will bring in all th sci-fi fans.
Voyager of the Dawn Treader!
He can be a borg like Seven of Nine.
Reepicheep of Nine.
