if we’re pitching our own minecraft movie ideas heres mine:
keep it an isekai, make it animated, the main characters are siblings of different age groups (youngest hasnt played the game because her brother tells her videogames are for boys, middle kid is a bratty 13 year old obsessed with roblox and minecraft and fortnite, oldest kid is teen/college age and thinks minecraft is a lame game for babies)
start with all the obvious minecraft stuff, reacting to floating trees, trying to go in a cave and getting scared off by a creeper, etc. they find their way out onto an online server, play minigames and meet mcyt cameos and players with specific niches. throw in a 2b2t reference, make a mob vote joke, whatever. at some point it turns out that the oldest kid actually does have a history with minecraft and just didnt want to admit it because she grew out of it and theres a bonding moment.
they run into another player who yes fine can be voiced by jack black and hes like. a dude who was also isekai’d into minecraft years ago but lost his way out. he thinks if the kids beat the ender dragon they’ll be allowed back into the real world so they assemble a team and convince them they wanna beat the game because their little sister has never done it before.
yada yada the rest of the movie is just the normal progression of beating minecraft. eventually its whittled down to just the kids and jack blacks character. he sacrifices himself to give the kids a chance, they land the final hit, they wake up in the real world. epilogue is the older two kids introducing their little sister to gaming.
idk i just think you could make a movie thats 80% references to minecraft community jokes and 20% a story about a videogame bridging generations and it’d be fun. its a simple formula.
