Original cast members, directed by Tony Award winner Daniel Sullivan, including Anna Gunn as Marie, John de Lancie, Hugo Armstrong, Dan Donohue, Leonard Kelly-Young, Natacha Roi and Sarah Zimmerman stayed on for the week-long extension. There was no immediate word about a future life for the play, a labor of love written by Alda, who is a lifelong science buff.

The play "delves into the life and romance of one of the most brilliant female scientists in history," according to Geffen notes. "Famous for her groundbreaking research in radioactivity, Curie was the only person ever to win two Nobel Prizes in multiple sciences, but not without a struggle. For all the answers that come to her in the lab, Curie's life is peppered with questions of how to realize the passion she has for both knowledge and love. Celebrated but then rejected by the popular press as both a woman and scientist, Curie is left to define her place in society — and history — on her own terms."
