How Actors Remember Their Lines
In describing how they remember their lines, actors are telling us an important truth about memory.

This article explains that actors remember their lines by trying to remember the meaning of their lines.

"You must be able to stand there not thinking of that line. You take it off the other actor’s face. Otherwise, for your next line, you’re not listening and not free to respond naturally, to act spontaneously." – Michael Caine

Take this example:

Try to recall the name of the dwarf that begins with the letter B.

Some may find this difficult. But how about:

Recall the name of the dwarf whose name is synonymous with shyness.

Meaning helps memory.
