The Big Questions

 was a feature of the official BBC Doctor Who website that began at the start of series 4, and continued on throughout series 5, when it was slightly renamed, Big Questions.

A series of short video clips, it featured the lead actors — and occasional guest actors — answering written questions from viewers relative to particular episodes. They frequently displayed the off-screen chemistry between the actors, as the two actors usually were in the same room. However, some editions were clearly drawn from two or three separate interviews later cut together. Typical questions ran along the lines of, "Given that x is a part of this episode, how would you react if you had to deal with x in real life?"

An edition of Questions was made available for virtually every episode from Partners in Crime onwards.
