Night filming of the XF

They shot a scene with Gillian coming out of the building bumping into a guy dropping her phone. He picks it up and hands it back to her.

It took several shots and Gillian messed up and laughed and giggled.

David was also inside in his suit. While he said on te chairs with his phone in his hands Gillian was laying down on the chairs next to him.

So they are both on set filming for the night.
