I'll point fingers at Marvel and Kevin Feige, no problem. Seems like par for the course for the way they're handling the movies. Cue Brett Ratner for Iron Man 3!!!
I wonder if Downey publicly said all this, how willing they'd be to fire him and replace him with another actor.
Maybe Warner can give Favreau the directing gig of one of their DC movies, starring Edward Norton and Terrence Howard.
