"Lunch is for Wimps!" is a line from which film?

It’s hard to believe that this movie is 38 years old. The acting was so good in this movie.. Douglas performance was outstanding ,, and so was Charles, Darryl and Martin…

I went to work in a small privately owned bakery. They frowned upon lunch breaks. I always took one anyway. It was the law in my state. They didn't fire me. I was a hard worker.

I had never saw that movie
