Sam Bacile, a 56-year-old California real estate developer who identifies himself as an Israeli Jew and who said he produced, directed and wrote the two-hour film, "Innocence of Muslims," said he had not anticipated such a furious reaction.
Speaking by phone from an undisclosed location, Bacile, who went into hiding Tuesday, remained defiant, saying Islam is a cancer and that he intended his film to be a provocative political statement condemning the religion.
