What theater would you like to see Hellboy at?
At the Cinemark in Green Valley.
Do you have a time preference?
Yes. it has to be between 2 and 3 PM today.
There are no showtimes between 2 and 3 PM today for Hellboy. Would you like to try a different time?
How about after 3?

Are there any in 3D at that time?
There is a 3D viewing at 4:00. Would you like to order tickets?
None before 4:00 PM?
