Who could replace Michael Scott as the boss of "The Office," now that Steve Carell is leaving NBC's hot series after this seeason? The Hollywood Reporter says the latest rumor has Harvey Keitel as a prime candidate to fill in for Carell. Paul Lieberstein, who produces the sitcom, told E! News that Keitel "is probably the only guy who can do it, and he's doing TV now." Lieberstein, however, said he he has not yet approached the 71-year-old actor, who recently starred in the short-lived drama "Life on Mars." "I haven't started any talks with his people, but Harvey would do a great job -- a very different energy," Lieberstein said. "And we don't want to bring in another Michael, having someone play a very similar character because we have such a high regard for Steve." The idea of having this guy as their boss, though, must send shivers down Jim's and Pam's spines.
