I think the only way to make a decent Uncharted movie is to not have it involve any member of the Drake family. Have it be another character on a journey trying to find a treasure, they name drop it as a treasure Nathan gave up on as it was too difficult but our protagonist is too desperate. They even maybe find something belonging to Nate showing where he gave up along the way. Maybe have Anya Chalotra play Chloe who pops up for a bit.

If you were really daring maybe have them cross paths with one of the games, narrowly missing actually seeing Drake. But really just focus on new characters on new adventures. Characters who might later be picked up by the games. That way canon can be ambigious bla bla bla.

Thats the only way I see it being feesable to get a good movie out of this.
