In your close-up, as you think and speak, your head movement can follow a triangular pattern.

It looks good on screen.

And it’s part of film language. We recognize the pattern of the movement from movies. 

It’s also recognizable human behaviour. In life we make the same triangular movement, so it’s truthful and technically sharp. 

Can’t get any better than that.

It can go like this: the other actor sends you a line and as you receive it your head dips down and to the left as you’re thinking, and then, as your thoughts and words unfold, your head comes up on the left side. Finally, as you complete your point and dialogue, your head returns to its starting position on the right looking at your scene partner tight to the lens.

It’s a flowing, triangular movement based on your thought going from right, down, up on the left and then back again on the right.

Everything is in the detail.
