"And there's no way I'm going to do Dame Edna"

This quote by Miranda Richardson is an amusing method of revealing her aversion to take on the function of Dame Edna. Dame Edna is a character produced by Australian comic Barry Humphries, and is understood for her outrageous and eccentric habits. By saying "there's no other way I'm going to do Dame Edna," Miranda Richardson is indicating that she is not thinking about taking on such a role. She may feel that the character is too over-the-top for her to represent, or that she does not have the comical chops to pull it off. Whatever the reason, it is clear that Miranda Richardson has no intent of taking on the role of Dame Edna.
