Doctor Who: 11 Cool Details We Just Learned About Vincent And The Doctor
7. Matt Smith Improvised This Line - Or Did He?
Midway through the episode, the Doctor finally manages to get Vincent to go and paint the church, with the artist setting up his easel just outside the window that the Krafayis will soon appear behind.
Here, the Doctor - who isn't used to sitting around and waiting - grows extremely bored, and starts rambling on about random things, in an effort to pass the time.
One of the lines he says during this scene is "I remember watching Michelangelo painting the Sistine Chapel. Wow! What a whinger", and according to Curtis, there was something about this piece of dialogue that he just couldn't get right, and so, he ended up rewriting it over and over again.
The writer also revealed that Matt Smith "probably" improvised it. We're not sure why he can't definitely remember if he improvised it, but it's been so long since the episode aired that perhaps Curtis has forgotten what he wrote on the page.
