This movie is one of my all time favorites. I saw it when it first came out in the 1970's and thought it deserved more praise than it got. It is mostly an entertainment comedy with such lines as "You weren't that hard to find. You were standing in the middle of town with a rope around your neck." I read someplace where Mary Steenburgen had been working as a waitress in an Arizona dinner and Nicholson stopped in and thought she would be perfect for the part. I think there is some very touching scenes between Nicholson and Steenburgen that are well written and acted. Except for Christopher Lloyd the rest of the cast is wasted. I think the only reason John Belushi is in the movie is because Nicholson wanted to meet him. At that time Saturday Night Live was considered radical chic.
