Billion Dollar Brain Ratings & Reviews

  • TubzOctober 17, 2025
    Caine/Palmer is back and going solo, in a clever and maybe a little far fetched thriller, keeping pace with the technological changes of the time. Well worth spending time watching.
  • Drunken Monkey KombatJanuary 1, 2026
    Possibly the weakest of the original Palmer trilogy.
