The editor of the Washington Post during Watergate, Ben Bradlee, has apparently scowled at the film version of Nixon, as reported in the Washington Times (and then Drudged):
Mr. Bradlee, who appeared grim-faced during the film, was having none of it. “They [the filmmakers] never should have let him apologize in the film,” he said tersely after the screening. “Nixon never was sorry for what he did.”
Mr. Bradlee, of course, was executive editor of The Washington Post in the 1970s and managed Bob Woodward and Carl Bernstein’s reporting of the Watergate break-in and cover-up, the scandal that culminated when Mr. Nixon resigned from office in August 1974 rather than face almost certain impeachment and conviction in Congress.
The same paper offers up this tidbit of Ron Howard comparing Nixon to Bush.
