Sometimes a performer finds the perfect role, or the perfect role finds her. Maybe it's karma or the planets' alignment. Maybe it's sheer luck or hard work -- or all of the above. Whatever the reason, Claire Tyler was the right actress in the right role as JC333 (Jaycee Triplethree), the android actress heroine of Alan Ayckbourn's dark fantasy Comic Potential at Actors' Playhouse. Tyler's performance clearly delineated JC's slow awakening to some hidden core of humanity. Her 'droid's awkward movements began to turn into some kind of nascent grace, and her squawk-box voice mellowed into something musical. The role also had a theatrical dash, as when Jaycee went haywire, spouting bits of long-past performances that had somehow been stored in her hard drive. Tyler has been very fortunate in her short theatrical career, working with top area directors and with excellent scripts. Besides her fine work with David Arisco in Comic Potential and the recent Sherlock's Last Case, she also scored in a trio of Joe Adler productions at GableStage: The Shape of Things, Popcorn, and The Play About the Baby. But it is the android with a heart of gold who remains the most memorable role of her young career.
