Action man Sylvester Stallone and comedians Chris Rock and Garry Shandling have been named among a list of potential witnesses in the trial of disgraced private investigator Anthony Pellicano. The stars are just some of the celebrities who allegedly had their phones bugged or names illegally checked against police databases on the order of Pellicano. The spy has pleaded not guilty to federal charges in a 111-count indictment, including charges of conspiracy and police bribery. He is alleged to have been collecting information on celebrities for his clients to use for threats or blackmail. The prosecution's extensive witness list, baring 127 names, was unveiled on Wednesday as jury selection was completed in the case. However, Stallone, Rock and Shandling may not be summoned to appear in court as it is unclear just how many of the witnesses will actually testify, a note made by U.S. District Judge Dale Fischer. The trial is set to begin with opening statements on Thursday in a Los Angeles court. Pellicano, 63, will represent himself against the charges.
