Allow me to recommend one movie from these three genres: documentary, fantasy-comedy, and animation. It is so hard for a movie lover to compare apple to orange to mango and pick only one?! :)
Documentary recommendation: Years ago I accidentally discovered in my university AV library (ok, not that kind of AV :) ) this documentary series in film (yes, physical film in cans and movie projector) and it remains my favourite documentaries. In this UK Up Series of documentaries, you will get to meet 7 British boys and 7 girls when they were only 7 years old in the first film. And then the magic of this series is the filmmakers come back to revisit the lives of these 14 girls & boys every 7 years! I last watched them in the eighth film in 2012 when the “kids” were now 56 years old. Yes, 56! Next time we see them will be in 2019 when they are 63! It is almost a “longitudinal study” of people long before the madness of “reality TV” entrap us.
Here is the first film Seven Up! and they were all so adorable!
Fantasy-comedy: Groundhog Day (1993) is a fantasy-comedy film starring Bill Murray, Andie MacDowell, and Chris Elliott. Without giving you too much spoilers, Murray found himself caught in a time loop, repeating the same day again, again, and again! LOVE this film.
Animation: Howl’s Moving Castle (2004) written and directed by Hayao Miyazaki was an animation film that I just borrowed a Blu-ray to re-watch again (with some bonus features). It is only in recent years that I realized this film was loosely based on a novel by a British author. And I learned to love both the Japanese original Japanese voice stars which includes Takuya Kimura (木村 拓哉) as Howl and English voice stars which includes Christian Bale (Batman Begins, American Hustle, The Big Short) as Howl, Emily Mortimer (Match Point, Dear Frankie) as young Sophie, Billy Crystal, and Lauren Bacall.
P.S. As a documentary filmmaker, I really LOVE the Up Series but to be honest and blunt, given our current ethical standard re informed consent, I can’t ethically agree to the making of this series of films knowing that 7 years old girls and boys can’t really give that kind of informed consent and the intrusiveness of this series.
