Harry Potter movies have entertained the audiences since 2001 when Harry Potter and The Sorcerer’s Stone was released. Since then it has sucked us up in a world of magic and mystery, and we haven’t been the same.


But just because the movie has people doing in it, does not mean it is just as easy to portray in the reel. And thus came the introduction of some really handy people who can help with the CGI.
