It could be with that strike of business workers that was about to begin today but apparently, they made a deal, which is not too good, from what I understand. So maybe they just want to avoid delays? Rumor is that Tom filmed for Strange last January/February but who knows how big his role is. I guess because Waldron basically rewrote the original script, it could be more than just a cameo but who knows.
I think so, too (mid 2022). Given also that Sophia is pregnant, she will also then need some time to spend with her child, get to shape...I seriously doubt they could shuffle schedule around that much. I don´t mind, really, as I understand they basically take shows and miniseries as movies (same budget) so this is basically a pre-production for a movie.
However, I think they already have a director, they just didn´t tell us.
But we have TES to look forward to fill the gap. Since Tom seems to get out into a daylight more these days, maybe we will hear something new in following weeks or so
Also, let´s hope for some news, photos and maybe videos from the comic con this weekend.
