How could a director of a midsummer nights dream help the audience distinguish between Lysander and Demetrius?
Costume
Hair colour
Body shape (fat, built, skinny)
To distinguish between Lysander and Demetrius the director of a midsummer night dream could give the characters different appearance and body build. It can be very difficult to tell two actors apart, the director could give the characters different coloured hair, different costumes and have a different body shape.
Firstly an easy way to tell two characters apart is their build, for example someone who is well built is easy to tell apart from someone that is fat or skinny. The director could have some one fat play Demetrius and someone skinny play Lysander or visa versa.
Secondly, another good way to tell actors apart is by what they are wearing, for example rich extravagant clothes or threadbare rags that barely cover the body. Someone like Demetrius could wear fancy expensive clothes while Lysander could wear simple cheap clothes.
Lastly a good way to distinguish between Lysander and Demetrius because of their similar roles would be hair colour. Someone like Lysander could have red or blond hair while someone like Demetrius could have black or brown hair.
In conclusion there are many ways to tell apart characters whether it be by hair colour, physique or clothes. A director of a midsummer nights dream could do these things to make it easier for the audience to tell characters like Lysander and Demetrius apart.
