The answer is simple a jew can smell money a mile away (hence the massive nose) and in hollywood there is alot of money, so a jew will try to get his/her foot in the door (so to speak) so they can shove some of the hollywood fortune into their matress, they will try to work in Hollywood even if they hate acting/directing/ect, because the smell of money supersedes it by far. So there you have it, a simple and effective answer as to why jews are more previlant in Hollywood.

That algorithm for success is called tribal nepotism and the show-stopping accusation "anti-Semite!"

Yes, Jews Really Do Control Hollywood. So What?

The problem is that Jews undergo a lifelong process of tribal indoctrination. The inevitable consequence is that having control of the media industries allows Jews to push their indoctrination onto others (maybe without even really recognizing that they are doing so).

Consider that it was the Victorian Christians who introduced the English-speaking world to routine genital mutilation (something euphemistically called "circumcision") in order to curb masturbation and sexuality, an idea they stole from the beloved Jewish "Torah scholar" Maimonides.

However, this routine violation of human rights in the English-speaking world now takes place almost exclusively in North America (mainly the United States). Why do you think that is?

The biggest reason is that a society's media industry shapes public opinion, and Hollywood has a had a long history of pushing circumcision on the American public through TV and movies and incessant articles.

Similarly, Jews in the medical industry are strangely enthusiastic and vocal about pushing their ritual genital mutilation as a matter of general public policy; this is discussed by the Jewish anthropologist and physician Dr. Leonard Glick in his book Marked in Your Flesh: Circumcision from Ancient Judea to Modern America.

In general, humans' most prevalent [mis]feature is their inherent capacity to compartmentalize the world into in-groups and out-groups; this is why it is dangerous for any particular group of people to attain control over an aspect of society—especially one as influential as the media industry (and medical industry for that matter).
