Marvel's notoriously tight leash on its filmmakers has sent everyone from Jon Favreau to Edgar Wright packing, but it seems as if the studio is finally learning to loosen its grip. While I hardly think we're on the precipice of a kinder, gentler Marvel, they certainly seem to have learned that it's damaging to their reputation to continually hamstring their directors. If Thor Ragnarok director Taika Waititi is to be believed, he was able to ignore the rest of the MCU entirely while making the film.
Waititi did an AMA on Reddit this weekend and let slip some interesting tidbits about the upcoming Thor threequel, namely that he was able to shut everything else out and focus on the film at hand. When asked how the events of Ragnarok were going to affect the entire MCU, Waititi responded, “I honestly know NOTHING outside of what I’m doing. I’m trying to ignore the rest of the universe and just make my own awesome movie.” He later drove the point home saying, “I made an effort to ignore the fact that there are other Thor films.”
Another interesting indication that Marvel is softening came in his response to this question—Can we expect some of the same brand of humor in Thor? If so, were you ever given a hard time about certain scenes or lines?—to which he responded, "You can expect a Taika-esque tone. They've been very accepting of my style." So that's another good indication that Marvel has learned that too much meddling sends talented people running for the hills—or, god forbid, for DC.
Again, take all of this with a grain of salt, as I'm sure Taika is happy just to have a directing gig as huge as this one. He may be making Marvel's acceptance of his tone out to be better than it actually is, but I certainly think that Marvel is making progress.
