This troper was once involved with a production of ''The Comedy of Errors'' where we had two sets of "twins" who were actually similar in build and appearance. Then one of each set had to drop out. We ended up doing some cutting and lightning costume changes, and using a framing device of a child playing with large rag-doll puppets - which we used for the scene where the twins meet face to face. (The girl playing the child walked in and out of every scene, moving props around and occasionally "pushing" the actors into place).

It worked surprisingly well.

This (other) troper was involved in a different production of ''The Comedy of Errors'', where the two Dromios were played by one actor. (He had a vest that he would reverse when he switched from one to the other.) In the last scene, where the twins meet, we had a bit of fun with it by having one of the Dromios played by the only African-American member of our cast.

This troper once saw a production of ''Seven Brides for Seven Brothers'' where six of the brothers were white, and one was black. Not actually twins, of course, but still quite striking.

My friend's brothers are twins, and they are completely non identical and barely even look like brothers. One is really tall and ginger, and the other is short and thin with dark hair.
