The unknown Joel and Ethan Coen wrote the pivotal character of a detective in “Blood Simple” for Mr. Walsh. To their surprise, and despite offering little more in compensation than a per diem stipend, he accepted the role.

On the set, he took pleasure in hazing the neophyte directors. “Let’s cut this sophomoric stuff, it’s not N.Y.U. anymore,” Joel Coen recalled him saying, according to a Times article in 1985. “One time I asked him to do something just to humor me, and he said, ‘Joel, this whole damn movie is just to humor you.’”
