Mary Birdsong, Candy Buckley, Jeffrey Carlson and Christopher J. Hanke are among the cast of the developmental staging of “Tales of the City” at the Eugene O’Neill Theater Center in July.

Thesps were announced as part of a list of ensembles for the works to be showcased during the O’Neill’s summer developmental conferences for plays and tuners.

“Tales” — a brewing adaptation of the Armistead Maupin stories with music by Jason Sellards of the band Scissors Sisters, book from Jeff Whitty (“Avenue Q”) and direction by Jason Moore (“Avenue Q,” “Shrek the Musical”) — reps one of the higher-profile new legit offerings at the O’Neill this summer.

Johanna Day (“Proof”) will appear in the latest play from Pulitzer Prize winner Nilo Cruz, “The Color of Desire,” helmed by Playwrights Conference a.d. Wendy C. Goldberg.

Day also will star with Lynn Cohen and Dick Latessa (“Hairspray”), among others, in director Mark Brokaw’s staging of Julia Cho’s play “The Language Archive.”

The O’Neill conferences, which include another tuner (“Picnic at Hanging Rock”) and seven plays, run from late June through July.
