I was going to watch this then noticed...
...that Richard Dreyfuss isn't even in it. It's not American Graffiti without him. He obviously saw the wisdom in staying out of this one.
I'm surprised they got Harrison Ford in 1979 with him busy on The Empire Strikes Back. I notice though that his name is not in the credits, no doubt a conscious choice.
