In some cases such as with Star Wars and MCU flicks the actors sign a contract which allows any licensing for the movies to use their likeness on products.
However on smaller movies by default the actors all need to be paid royalties for their likeness from a licensor. So if NECA wanted to make Blade Runner (original) figures they would need to pay money to Ridley Scott, the company that owns and distributes the movie, and then to the actor for each character. Which is not only a giant pain in the ass but also possibly cost prohibitive considering what kind of profits they see in it.
Now NECA have done this in the past, obviously, but it's possible that the fee to use Harrison Ford's likeness is what's holding this one back as he is a much bigger name than the actors from say the Alien/Predator movies and similar.
