The following are some suggestions for plays to look at with scenes for two actors. This list is taken from/inspired by the list in More Duologues For All Accents And Ages, and it skews a little British, but you can find similar lists in any of the books on the previous pages. This list is meant to be a starting point. Also, your instructor may have suggestions for scenes or monologues which are different than the ones listed here.
We've organized them according to the genders of the actors. We have copies of many of these plays as separate texts. Also, many of these can be found in the collections of scenes or duologues which the library owns. Look them up in the I-Share catalog, and ask at the Reference Desk if you need help!
