Action-filled chapter as we get to see the war/riot between ape and man. It is back to a more darker storyline and no humor is present. It was cut and re-shot by stupid worried producers at the time (but luckily everyone can now see the complete version on Blu-Ray!).
J. Lee Thompson's politically astute directorial effort put the apes films back on track after the dismal third film. McDowall now plays Caesar the child of Cornelius and Zera and the harbinger of the doom of mankind. Quite interesting and in turns exciting entry in the series. Well paced and featuring a one note but enjoyable performance by Don Murray.
