Robert Iler, 16, who plays Tony Jr. on the HBO mob hit "The Sopranos," and two other boys -- Michael Cournede, 19, and Alban Selimaj, 16 -- pleaded innocent Wednesday to charges that they robbed two teens of $40 on Manhattan's Upper East Side over the July 4th weekend. Prosecutors allege Cournede was armed with a box cutter. Iler entered the plea before Justice Laura Visitacion-Lewis in criminal court during his arraignment on an indictment charging him and his co-defendants with second-degree robbery, reports the Associated Press. If convicted, each faces up to 15 years in prison. Iler, who is currently free on $2,500 bail, also faces a possible $100 fine for marijuana possession. Judge Visitacion-Lewis agreed to lift a 10 p.m. curfew imposed on Iler, who needs to fly to California for work, said his attorney. Iler's next pretrial court appearance has been set for Oct. 5. Meanwhile, in Chicago, a hearing to dismiss the American Italian Defense Assn.'s anti-defamation lawsuit against "The Sopranos" was heard on Wednesday in Circuit Court of Cook County, Chicago. The hearing, open to the public, represents the latest installment in an ongoing battle between the producers of the show and the advocacy group AIDA. It has said that the critically lauded Emmy-winning series constitutes cultural defamation and is in violation of provisions regarding individual dignity and the Illinois constitution. Judge Richard A. Siebel said he would issue an opinion Sept. 13 on whether or not the lawsuit can go forward.
