As the terms mime and pantomime are so often used interchangeably, they will be treated as synonymous except in the case of English Pantomime, which will have a sub-category of its own.

The working definition of mime for this category will be: The dramatized representation of life, performed for an audience, in which the primary means of the actor's expression is physical, and where this physical expression takes significant prominence over verbal expression.
