WASHINGTON — After complaining for weeks that the movie “Zero Dark Thirty” erroneously implies that torture yielded key information in the hunt for Osama bin Laden, a trio of senior senators now want to know whether CIA personnel deliberately misled the filmmakers on that point.

Sen. Dianne Feinstein (D-Calif.), chair of the Senate Intelligence Committee, along with Sen. John McCain (R-Ariz.) and Sen. Carl Levin (D-Mich.), said Thursday that they had sent two letters to acting CIA chief Michael Morell. In the first, dated Dec. 19, they requested information about what the CIA told the filmmakers. In the second, dated Monday, they asked Morell to clarify a statement he issued on Dec. 21 about the movie and its portrayal of torture.

The senators believe the Sony Pictures film wrongly suggests coercive interrogation was instrumental in tracking down the Al Qaeda leader, and they believe the filmmakers got that misimpression from CIA officials.
