Karl Miller, Mandy Siegfried, Brooke Bloom and Johnathan McClain are featured in director Pam MacKinnon's production.

According to SCR, "The couple at the heart of Completeness are grad students. Elliott (Helen Hayes Award winner Karl Miller) is a computer scientist searching for an answer to the elusive Traveling Salesman Problem; Molly (Mandy Siegfried, of Broadway's Noises Off) is a microbiologist studying protein interactions. A chance meeting in the library leads to a scientific collaboration that turns romantic. But they soon realize that love is more complex than any scientific problem they've ever encountered."

Playing the various ex-girlfriends and ex-boyfriends who complicate Molly and Elliott's relationship are Bloom (SCR's Hamlet and A Feminine Ending) and McClain (TV's "Retired at 35," Lincoln Center's Spinning Into Butter).

MacKinnon directed SCR's production of Becky Shaw earlier this season, as well as Our Mother's Brief Affair in 2009. She recently directed Death of a Salesman at The Old Globe and is a frequent interpreter of the plays of Edward Albee, having directed premieres of Peter and Jerry (now called At Home at the Zoo, Hartford Stage and Second Stage Theatre) and Occupant (Signature Theatre) as well as The Goat, or Who is Sylvia?, The Play About the Baby, A Delicate Balance and Who's Afraid of Virginia Woolf?

This is Moses' second play at SCR. His first was 2006's Bach at Leipzig. His other full-length plays include Outrage, Celebrity Row, The Four of Us, Yellowjackets, Back Back Back and The Den, as well as a musical adaptation of Jonathan Lethem's The Fortress of Solitude (with Michael Friedman). He writes for television’s "Boardwalk Empire" and "Men of a Certain Age." The creative team consists of Christopher Barreca (set), Sara Ryung Clement (costumes), Russell H. Champa (lighting), Bray Poor (sound), Kelly L. Miller (dramaturg), Jackie Hill (production manager) and Jennifer Ellen Butler (stage manager).

Opening is April 22. This play is a recipient of an Edgerton Foundation New American Plays Award. Performances play SCR's Julianne Argyros stage.
