can you give a screengrab of the 3 shots you are referring to? I assume one of them is the following scene:
I'll go ahead and proclaim that there is essentially no good way to remove anakin from this scene. Scenes I had like this in my Harry Potter edit, I've just decided to skip.
1. If a character is at the edge of a scene, he can be cropped. He's in the center here, and so huge that a crop would turn 1080p down to worse than 480.
2. If he is in front of a static background, you can sometimes recreate the background in photoshop and actually use the still frame as a mask. This would generally involve taking a screen grab, then using the clone tool and healing brush in photoshop, bringing this back into your editing software, and using a mask so you only use your image over a static non moving part of the clip, and allow whatever other action to happen still proceed.
3. If there is a moving camera, number 2 won't work. You can then try image tracking to move your frame, which can work. Trying to edit frame by frame will end up quite jittery.
Unfortunately, you've got a moving background, moving characters that are sometimes fully visible and sometimes partially hidden, possibly a camera zoom - I think its too much. Even if you could edit a single frame to make it look good, you can't just edit each frame individually, when you play them together it'll be really jittery.
Not sure which other shots you are trying for, but for this one, I really think you may just have to cut it.
