While the era of the roadshow engagement is long gone, I couldn't help but notice some remnants are coming back. Advance tickets were available. Granted, there was only one screening in this case. You could still buy them in advance. You could also choose the seat you wanted, similar to reserved seating during the initial engagement. They also including the intermission.
Unlike the roadshow engagement, I bought the first ticket for the screening 30 minutes before showtime!
