Remove moving boy

i want to remove the boy wears green,he across the picture.but at the same time,the blue man at the background also moving.

 

after remove like this

give me some suggestion how to sovle the problem?

There is no real way to fix this issue other than painting clean plates, because the man in the background is moving while the boy is crossing over him and there are no reference frames to compare to his previous stance, nor is he moving in a planar way.
Normally with backgrounds that have multiple levels of parallax you need to roto out each element separately, but the man is bending over and standing up, which is not as simple to use as replacement.

You may just have to paint him back to position for the bad frames.

the picture in this page3 pictures

thank you.i see the way.it’s hard to me to do that,but i try my best.
