There's a point to all this. Bear with me. Here's the trailer.
"Based on the movie, Snowpiercer, directed and co-written by Bong Joon Ho, creator of the Oscar-winning Best Picture, Parasite."
The movie Snowpiercer is absolutely terrific, a dazzling, tour-de-force 2013 film that won 33 international awards. Why on earth they don't mention the TV series' connection to this year's Oscar-winner is beyond me. Perhaps because it's on a foreign film, but I doubt that because countless TV series have been based on movies -- and few (if any) based on Oscar-winning Best Pictures. Maybe because the original source is a French graphic novel and they only bought the rights to that -- though I find it hard to believe that they wouldn't buy up all the rights.
By the way, although a Korean movie, it was in English for its international release and had an impressive cast, including Chris Evans (from Captain America and the Avengers movies), Tilda Swinton (Oscar-winner for Michael Clayton). Jamie Bell (who played Elton John's songwriting partner Bernie Taupin in Rocketman), John Hurt (two Oscar nominations for The Elephant Man and Midnight Express), three-time Oscar nominee Octavia Spencer,(who won for The Help). and Ed Harris from The Truman Show, Apollo 13 and Oscar-nominated for Pollock. Even one of my faves, the wonderful Allison Pill (from HBO's The Newsroom and currently Star Trek: Picard and Devs) has a small role.
The iMDB description of the film is "In a future where a failed climate-change experiment has killed all life except for the lucky few who boarded the Snowpiercer, a train that travels around the globe, a new class system emerges." In fact, like Bong Joon Ho's Parasite, the film has a strong class warfare center -- with a heavy emphasis on the warfare.
Here's the trailer of the original movie. It doesn't do the film justice, but you'll get a good idea. And it's highly recommended. And yes, the movie is included on my list of train movies that I post every National Train Day.
