Author! Author! (1982)

One reason you may not have heard of this movie is because it’s not currently streaming anywhere and it’s really tough to get ahold of even a DVD copy of it. But if you can manage to see it, it’s a totally worthwhile little picture.
In Author! Author!. Pacino plays a struggling playwright who becomes the de-facto father of a group of unwanted step-children left in his care from past relationships. He’s a great single dad and his step-children love him.
It’s full of funny little moments, like when his producer friends ask to bounce an idea off of him: “Let me bounce this off you, and that off you!” he yells back, throwing scripts at them.
Please, I need more people to watch this movie so someone will understand my niche references.
