Answer:
Assuming this is theatre actors, if not by bad loll.
Explanation:
3)Improvising- Really important if the actor themselves or another actor forgets lines
4)Facial Expression- Makes the character played more believable
5)Memorization- Remembering lines to get off script quickly as possible or by a certain date
6)Emotion in voice- It's important to be heard, but equally important that the actor's voice does not sound bland/uninterested as it makes the play boring
7)Knowing basic theatre etiquette, such as knowing how to stand on a stage(never stand face your back towards the audience)- Really makes or breaks the show because it is really awkward to have actors face their back to the audience
8) Open to new ideas/criticism- Actors need be open to new ways of doing a scene and not be stubborn on doing it their way only as it's not always the best way
