You can skip 2 of the 3 drawbridge cutscenes near the start of ET. If you're in the air for long enough it will cause you to start "falling" making the cutscene end for some reason. I do this on the 1st and 3rd cutscene. The first 2 cutscenes are 4 seconds long each, but the 3rd one is 8 seconds. The first one can be done RTA for sure, 3rd one with a longer setup on the stairs should work as well.
