>>86684344John Lasseter and Ed Catmull are key executives at Disney proper nowadays though, if they feel Pixar should cut back on the sequels (as they seem to) then they can fight corporate and win, Disney absolutely needs them.
The real risk is the men themselves becoming sellouts, Toy Story 4 seems to be a sign of that but in reality the interviews really make it seem like Lasseter's making it because he wants to, he just seems to be a manchild who has a lot of fun playing in the same "toybox" so to speak, Cars was his idea too. I do bet that Disney shareholders pushed for it though, as whenever a movie grosses a billion dollars (as TS3 did) a sequel is deemed necessary and inevitable in the current production environment.
But I do really hope that after TS4 stockpiles them another cool billion they'll live up to their word and stand up and make an effort to take risks like their 2007-2009 hot streak again, after all there's absolutely bound to be reboot/remake/sequel fatigue eventually (every movie trend has a limited lifespan), and it would be a smart move on Pixar's part to be there with their respected brand name when the market changes. After all, Inside Out didn't do too shabby at all.
All that being said, The Incredibles 2 written & directed by Brad Bird is something we all wanted this whole time anyway, so something good came out of this profit-minded bullshit.
