We used the photographed area due to the space and proximity within the building.

As shown here, the space to portray the characters properly is of a significant size, making what they wanted to act out a huge amount easier.

As well as the space being big, the environment the scene is set within makes this particular section of the building a good match for the scene to be filmed. The surrounding classrooms help in this cause.

This toilet used is for when the male main character applies the hair gel marketed within the ad.

The man applies the gel on this set of sinks pictured here.

Through a bit of clever camera work, the loos look like their behind the door shown in an above image-this certainly shows the atmosphere of a school building in its fullest.

The final bit of the scene will be filmed within the space, shown here and mentioned in above pictures.

As this bit is supposed to be really chaotic, the space as seen here makes the area a good match for what we wish to film.
