Eastwood was given a number of scripts, but he ultimately reverted to the original as the best vehicle for him. In a 2009 MTV interview, Eastwood said "So I said, 'I'll do it,' but since they had initially talked to me, there had been all these rewrites. I said, 'I'm only interested in the original script'." Looking back on the 1971 Don Siegel film, he remembered "[The rewrites had changed] everything. They had Marine snipers coming on in the end. And I said, 'No. This is losing the point of the whole story, of the guy chasing the killer down. It's becoming an extravaganza that's losing its character.' They said, 'OK, do what you want.' So, we went and made it."
