Люпин в оригинале выглядел, вроде, вот так...
Remus is described as having a pale face with premature lines, and light brown hair that, with each book, becomes more and more grey. The lines on his face and his greying hair were the results of the great deal of stress his body underwent with each full moon. His clothing is consistently shabby and patched, presumably because of his inability to find a decently-paid job due to his status as a werewolf.
In 1993, he sported a thin moustache, and from 1995 until his death, he sports more of a rough beard. He has scars cutting across his face and given Remus' comments on werewolf inflicted injuries being cursed wounds that are unlikely to fully heal after Fenrir Greyback's attack on Bill Weasley, it is possible he bears more scars from his self-inflicted injuries during his transformations. In death, however, the flaws of his appearance were rectified, just like his friend Sirius Black; his spirit was described as "younger, less shabby, and his hair was thicker and darker."
