I remember that line very well, and I haven't seen that movie but once when it came out. How long ago was that, 50 years?I can't help but remember in the movie "The Graduate" with Dustin Hoffman..... In the first couple of minutes into the film, Ben (his character) was in the swimming pool and a business friend of his dad was talking to him about what field he should go into to make a good career & a lot of money......and he told him "Plastics.....go into plastics because it's going to be really big one day". Sadly, someone in the audience took that piece of advice & ran with it.
