Afaik the following featured in the trailers/tv spots and didn't make the cut at all or were reduced to background TV screens:
Completely cut:
1) The Thing dropped from a plane.
2) The plane itself (looked like a Stealth bomber).
3) (presumably) The Thing landing in that scene on a Jeep.
4) The Thing emerging from rubble, striding along while being shot at.
5) Torch's 'big ass sunroof' quip.
6) Reed talking with a prone Doom in the lab.
7) Human Ben playing baseball and smashing the neon 'Grimm' sign.
8) Sue looking all sad over a prone Johnny.
9) Ben sizing up a hay-maker for a prone Doom.
10) Extended shot of Johnny in flight (presumably from the drone sequence).
11) Sue & Johnny teaming up on smashing one of those column things.
12) Johnny kneeling flamed on and lighting up the corridor.
Reduced to background tv screens:
1) Infamous flash paper tank turret and other shots of the Thing smashing some stuff and people about (accompanied by his 'confirmed kill count'...
).
2) Johnny tossing some fireballs at targets.
3) Sue playing with some cargo boxes.
And one thing clearly altered: 'Planet Zero' went from red lava to ugly green ooze in post.
There was probably some more stuff but that's the ones I know of.
