The movie is disgusting. They made it in the name of freedom of expression. Only third-rate idiots will believe lies in this movie.
Read seerah, the pagan Quraish did all they can to ridicule Prophet Muhammad (blessings and peace be upon him), in fact the Prophet Muhammad (blessings and peace be upon him) was physically harmed. But it never stopped disbelievers becoming believers. Despite all the hostility, hatred and persecution by the pagans never the Prophet Muhammad (blessings and peace be upon him) took revenge upon them after the opening of Makkah. Previously there was publicity stunt movie call "Fitna", the maker of the movie is now an elected representative in his country. Whatever movies being made and lies being said about the Prophet Muhammad (blessings and peace be upon him) at the end they achieve nothing. Because the objective of this kind of movies nothing but to discredit Prophet Muhammad (blessings and peace be upon him) and in the process they are hoping to achieve two things:
1) to weaken Muslim Ummah
2) to distance others from reverting to Islam
I don't think they are achieving the above because Allah said in the Qur'an:
"And (the unbelievers) plotted and planned, and Allah too planned, and the best of planners is Allah." [Al-Qur'an, 3:54]
These movies are nothing but paganism and act of immature people. However as Muslims, we must show maturity. We've to protest and show our anger towards whoever behind making of this stupid movies. But bear in mind that we should not address paganism with paganism, stupidity with stupidity. Burning and scaling down US Embassy and violence protest is not the answer. I regret to read that US mission in Egypt and Libya was attacked and lives were lost.
May Allah punish those idiots who made the movie.
Allah knows best.
