R2 laughing at 3PO tangled up was originally right after they cross the hallway during the shoot out at the beginning of the film. The film cuts away at the explosion, but that’s where the shot of 3PO tangled up originally went.
Thanks!
So that explains why 3P0 was later looking for him…
The ones during the chess game although I am not absolutely sure so don’t hold me over a Barrel but might go when Chewie is having his handcuffs put on him. At the end R2’s head changes position a few times. Not anything particularly earth shattering in any case. 😃
I have not checked this so unconfirmed but my gut tells me it’s around there somewhere…
