Years ago, after a premiere or the Academy Awards, celebrities were always seen entering but not exiting the Chinese. Reason being, there was an underground tunnel that led accross the street to the Roosevelt Hotel (Sid Grauman had an interest in the hotel also). That way, celebrities could leave anonymously. The tunnel had not been used in the past 30 years. The tunnel is gone, and access to it from either the theatre or hotel was sealed up when the subway between the two building was built under Hollywood Blvd., a couple years ago.
