Bankrupt movie-theater chain Cineworld Group PLC said it continues to miss its box-office projections due to challenging market conditions as it gears up to sell itself out of chapter 11.  

Joshua Sussberg, a lawyer for U.K.-based Cineworld, owner of Regal Cinemas, told Judge Marvin Isgur of the U.S. Bankruptcy Court in Houston, Texas, on Wednesday that the company’s restructuring effort since its bankruptcy filing in September has been hindered by the lackluster box-office performance.
