From what I have noticed, many fanticise over it, but all is not glitter.
But the only way to get it out of your system is to go out and try it. Am sure that your buble will burst and you will not be rich and famous for it. I have turned down big bucks for two weeks rental of my tracked vehicle, ($12,000) to be exact as there is no guarantee your vehicle will not get abused. Remember, movies are not shot in your back yard, and then there are logistics to factor in.
Everyone wants to be a movie star, go for it, for most, it will be a dream.
