Batalla por el planeta de los simios

One decade after a worldwide series of ape revolutions and a brutal nuclear war among humans, Caesar must protect survivors of both species from an insidious human cult and a militant ape faction alike.

Screenwriters John William Corrington and Joyce Hooper Corrington were brought in after the success of their film "The Omega Man", although prior to that neither one of them had written any science fiction films and, indeed, Joyce Carrington later admitted they had never seen any of the Apes films prior to being hired to write the script for "Battle".

Roger Ebert gave the film a negative review, stating, "Battle looks like the last gasp of a dying series, a movie made simply to wring the dollars out of any remaining ape fans." As usual, Ebert is spot on. This feels nothing like an "Apes" movie at all, and the continuity starts to get a little strange. Even ignoring the paradox of the time loop, there is no explanation of how the apes became able to speak and so forth. If Caesar had a mate and this was 500 years in the future it might make sense, but apes simply do not have the ability to speak!
