As I type this message, free tickets to attend the premiere are still available to print out here! If the tickets are still available by the time you read this message, it's important you arrive early. I'd recommend arriving 2-3 hours before the premiere starts.
Grauman's Chinese Theatre is located at 6925 Hollywood Boulevard and directions can be found here. You can park at Hollywood & Highland Center for 4 hours for $2.00 after validation (which you can get at the information booth without having to purchase anything). For further information, please call Grauman's Chinese Theatre at (323) 465-4847.
