Well, not really, but it's not a good place to start from. Was this sourced from DVD? If so, that's one badly produced DVD! I'd try and get hold of the PAL disc and work from that. If it's not from the DVD... well, same advice
Interlacing in itself is going to cause you some problems (is the whole project like that?), but your misalignment is probably mostly because you're limited to an accuracy of one pixel. Short of writing programs like I did, you could try scaling everything up by 4, or even 8, aligning your patch and then scaling back down (but then you should probably copy back in the original frame to get rid of any scaling errors, and memory may become an issue).
If it wasn't for that zoom at the end, and the interlacing, I'd happily knock up something to produce a patched version, which you could then mask more precisely around Richard Pryor...
