LOS ANGELES — Fuming for two months in a jail cell here, Nakoula Basseley Nakoula has had plenty of time to reconsider the wisdom of making “Innocence of Muslims,” his crude YouTube movie trailer depicting the Prophet Muhammad as a bloodthirsty, philandering thug.

Does Mr. Nakoula now regret the footage? After all, it fueled deadly protests across the Islamic world and led the unlikely filmmaker to his own arrest for violating his supervised release on a fraud conviction.

Not at all. In his first public comments since his incarceration soon after the video gained international attention in September, Mr. Nakoula told The New York Times that he would go to great lengths to convey what he called “the actual truth” about Muhammad. “I thought, before I wrote this script,” he said, “that I should burn myself in a public square to let the American people and the people of the world know this message that I believe in.”

In explaining his reasons for the film, Mr. Nakoula, 55, a Coptic Christian born in Egypt, cited the 2009 massacre at Fort Hood, Tex., as a prime example of the violence committed “under the sign of Allah.” His anger seemed so intense over the years that even from a federal prison in 2010, he followed the protests against the building of an Islamic center and mosque near ground zero in New York as he continued to work on his movie script.
