Doctor Who Dream Casting: Martin Freeman as the Doctor with Jennifer Lawrence as River Song

Leaning against the wall, with feet crossed over and arms folded, was a man River had never seen before. His features were round and his nose was awfully long. His hair was sandy gray and cut short enough to accentuate his large ears. The man kept smiling at her and laughed once or twice to himself as though he was thoroughly enjoying a personal joke.
Then, quite suddenly, he shouted over the crowd of graduates, “You miss me?”
Looking over her shoulder she did not see anyone respond, and no one in front seemed to take notice of him. “E-excuse me?” She replied in confusion.
“You. Miss. Me?”
She tilted her head and lowered her eyebrows. His gaze was too direct to be informal. It was very unnerving to see him stare at her so knowingly. “I’ve never met you.”
The man looked at the room before pulling something oddly shaped from his pocket. It looked very much like a sonic screwdriver with a few alterations. “Wait for it, just a little longer. I promise, it’s going to start really soon.”
