A surprising Birdy meaning in this hunt as flying theater. The first time I read about this type of theater that is flying duration the show or film. The seats of this theater, not 2D and 3D but that is 4D seats with great mechanism and technology that not only view the movie but these seats give you flying riding.
We can say for the Birdy, double action theater because there is one ticket and enjoy with two things.
What a great hunt @john-paul
