Mobile Suit Gundam II: Soldiers of Sorrow

Mobile Suit Gundam III: Encounters in Space
What they share
Both films are directed by Osamu Sekita, Yoshikazu Yasuhiko, Yoshiyuki Tomino, and they both carry the bittersweet, foreign gem mood tags, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Mobile Suit Gundam II: Soldiers of Sorrow, the second film will land in a comparable space — through a different lens.
What Mobile Suit Gundam III: Encounters in Space is
You pilot a teenage refugee named Amuro into the White Base’s 13th Autonomous Corps and the Principality of Zeon’s last fleet. Your mobile suit’s bullets ricochet off a Zeon cruiser during the decisive battle. Osamu Sekita layers the chaos with a story that keeps space wars human.
