I've come across this word before. It's not "hypocrite". But the definition of the word was very specific. Basically it's an adjective, it's something you call a person who's really into art; like for example movies and film making.
He keeps talking about it, loves Stanley Kubrick or Jean Luc Godard. He studies the craft and technique, and he criticizes his colleagues' films. He thinks his taste is superior, and that if he given a chance, he would shake the industry. But in reality, he doesn't practice it. He's all talk, but no walk.
What do you call that person? (It also applies to other art forms like music. - "Our local musician sucks. He just does covers of John Mayer and Jason Mraz songs. That's why our music industry doesn't progress because of people like him. I listen to David Bowie and The Beatles, if I knew how to play a guitar, I would totally rock it out". ... )
