Warner Bros. prepares for possible appearance by thesp

Warner Bros.’ security force is girding for possible theatrics outside the studio today if Charlie Sheen makes good on his vow to show up for work on the shuttered “Two and Half Men.”

Warner Bros. would not comment, but it’s expected that Sheen will be barred from entering the Burbank lot if he does attempt to go to the “Men” stage that has been his professional home since 2003. Sheen has been dropping hints in his many interviews during the past few days that he intends to take legal action in response to CBS and WB’s decision to shut down to the show for the rest of the season because of his increasingly bizarre behavior.

Martin Singer, the longtime showbiz litigator who has repped Sheen in the past, has not returned calls seeking comment.

WB brass are bracing for the Sheen circus to stop outside its gates in the morning, likely with camera crews in tow.

On the air, NBC News has an interview today on “Today.” NBC leapfrogged ABC News, which thought it had landed the first TV sit-down with the verbose Sheen; that will be fodder for a special “Charlie Sheen: In His Own Words” edition of “20/20″ on Tuesday, with clips to be teased this ayem on “Good Morning America.” ABC News correspondent Andrea Canning said Sheen told her that he “plans to show up for work no matter what’s going on.”
