Yup; you were played.
This guy is a 2-bit wannabe who has never worked a day in Hollywood. Its called "basic research". Before agreeing to take classes with anyone outside of an institution (which seriously, classes AT HIS HOUSE?!), look into their claims. If he truly worked on Harry Potter and Charlie and the Chocolate Factory (which is another bold claim; who WANTS to take credit for that s**t show?), his name should appear on the production staff team on IMDB, at the very least.
Bearing this in mind, I did the work for you and pulled up the producer list on IMDB:
Bruce Berman ... executive producer
Graham Burke ... executive producer
Liccy Dahl ... executive producer (as Felicity Dahl)
Katterli Frauenfelder ... co-producer
Derek Frey ... associate producer
Brad Grey ... producer
Patrick McCormick ... executive producer
Lorne Orleans ... producer (IMAX version)
Michael Siegel ... executive producer
Richard D. Zanuck ... producer
Any of those him?
