Walk and talk

It has been used as a prominent story-enhancer in numerous episodes of The West Wing, The Bill, House, Ugly Betty, ER and Grey's Anatomy.

The Walk and Talk technique is also often used as a way of combining exposition with a visual introduction to major areas (and their locations in relation to one another) that will be used in a production.

This use of the technique is regularly seen in opening scenes in the UK series Hollyoaks as a way of recapping current story lines and showing how the plot streams interrelate with the characters.

In the direct-to-video Family Guy movie Stewie Griffin: The Untold Story, a cutaway gag depicts Chris guest-starring on The West Wing and engaging in a "walk and talk" scenario.

The camera eventually pulls back to reveal that Chris is actually inside a giant maze like those associated with lab mice, and he becomes excited at finding a piece of cheese.
