He's not showy as an actor, but rather reserved, which is why he is so underrated. Alcatraz was his first real character study, and I don't think he quite believed me when I told him how good he was. He's modest and doesn't like to hear it. But I thought he was incredible. Even the critics said so. I think he's getting better, more assured. And he's more likely to gamble than he was a few years ago. Within limits, which he's aware of, he's as good as anybody.

Clint Eastwood, A Biography by Minty Clinch, p. 134-135)
When Don Siegel first read Richard Tuggle's script for
Escape from Alcatraz in early 1978, it had been seven years since he had worked with Eastwood. Siegel told his agent, Lenny Hirshan, that the part of Frank Morris would be "perfect" for another Hirshan client, Clint Eastwood, and Hirshan saw to it that Eastwood received the script. Eastwood was enthusiastic in his first response to Siegel, but then Siegel didn't hear from him for several weeks, during which time Siegel bought the script, arranged for rewrites, and worked out a deal with Paramount to produce the film.
Richard Tuggle, Carol Rydall and I worked hard on the rewrite. I thought it was in good enough shape to show to Clint. I still hadn't heard from him, which was somewhat strange. I decided ... to send him the script and a note asking to sit down with him to discuss it and his playing Frank Morris, if he was still interested. If he wasn't, which frankly would surprise me as he was born for the part, I would go ahead without him, which would keenly disappoint me.

A Siegel Film, p. 438)
Eastwood, along with co-stars Fred Ward and Jack Thibeau, gave Siegel some difficulty by insisting (against Siegel's better judgment) on doing their own stunt work, including climbing along the prison roof, sliding three stories down a bakery pipe and swimming in the San Francisco bay until the tide carried them away. However, Siegel knew from the beginning that Eastwood was "born for the part" of Frank Morris. Do you agree? Why does he fit the role so well?
