I worked as an extra for two weeks on the movie......I am there if you know where to look. It was an absolute blast. See I loved the book and the author, Martin Sheen was my teenage crush and Christopher Walken was one of my favorite actors at the time. I met them all and to tell you the truth they were the most down to earth people. In fact my friend told Sheen how I had had a bad case of teenage love for him and he took me out to lunch in Niagra on the Lake where most of the movie was filmed. It was just a case of fate for me meeting my faves of the time and I even got paid for something I would have done for free. It was an absolutely wonderful way to make a lasting life memory!
