When I was a kid I went to see the Lion King with a friend who never knew his father. I remember being really sad when Mufasa dies and it made me also feel sorry for my friend, lol.
it was made in a live action film in 2005
the video isn't as much of a trailer as much of the movie.
BUT... it worked, i believe (it was a while ago) they focused more on the aunt, i think cuz the kids wouldn't be able to carry such a movie and they needed a good actress to do it, so they got Matsushima Nanako, w/o her being the lead i think the movie wouldn't have been as good, go try it if you want to stab yourself with "feels", it's actually one of the few japanese movies (live action) that are good imo.
