Sorry to disappoint you and your cinematic notions, but hypnotism cannot force you to do things against your will (unless the hypnotist is pointing a gun at you but thats a stickup). You, an ordinary, law-abiding citizen, will not turn wild and go trashing peoples windshields when under hypnosis. You will still maintain your principles; even if instructed, you wont trample upon your religions holiest shrine. Your sense of right and wrong will remain intact. Nobody can make you strip in front of a crowd - unless you want to. ?
The hypnotist can only make suggestions that can alter your consciousness, making you more open and easily manipulated to a certain extent. People who have experienced stage hypnotism said that they can refuse to follow the hypnotists suggestions, just that its easier to follow him. This is so because the active, aggressive, decision-making part of the consciousness becomes timid when under a trance. So it is easier to just automatically respond to suggestions. To some extent, the hypnotist can control the actions and the way his subjects behave. Conversely, the effect of hypnosis also depends upon your motivation, willingness, and faith to make it work for you.
