If you loved The Door Into Summer, try Space-Time Traveler - Time Stranger
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Mori Masaki, and they sit in Animation / Romance territory. If that's the register that drew you to The Door Into Summer, the second film will land in a comparable space — through a different lens.
What Space-Time Traveler - Time Stranger is
A rogue time-jumper with a broken stabilizer turns modern Tokyo into a waiting room for history’s worst day. His unwilling passengers include four pupils, a teacher, and an obsolete van, all dragged through the firebombing of 1945 before arriving smack in the middle of Japan’s civil war. The neatest paradox is that none of them thought to pack snacks for 450 years of sightseeing.
