Ford was an antisemite, so such a quote is not out of character.
Many other sources attribute the quote to "The Dearborn Independent, 12-19 February 1921".
The quote is from two different articles. From The Jewish Aspect of the "Movie" Problem:
If this is true, it is chargeable to the Jews themselves, for Jews have always controlled the business. That it is true is probable, for the most zealous lampooners of the Jews have been Jewish comedians. Non-Jews fail abjectly in endeavoring to portray the character.
From Jewish Supremacy in Motion Picture World:
Who stands at the apex of this mountain of control? It is stated in the sentence: The motion picture influence of the United States—and Canada—is exclusively under the control, moral and financial, of the Jewish manipulators of the public mind.
It should be noted that Ford did not write all the articles himself. Wikipedia describes the process:
Ford did not write the articles. He expressed his opinions verbally to his executive secretary, Ernest Liebold, and to William J. Cameron [...]. Cameron had the main responsibility for expanding these opinions into article form[...].
