Incoming Broadway musical “Chaplin” has set the rest of its cast, tapping legit regulars including Jenn Colella, Erin Mackey and Christiane Noll to join lead thesp Rob McClure in the bio-tuner.

Like McClure, Colella (“High Fidelity”) also appeared in the musical’s preem at the La Jolla Playhouse in 2010. She’ll reprise her role as gossip columnist Hedda Hopper. Mackey (“Sondheim on Sondheim,” “Anything Goes”) will play Oona O’Neill, Chaplin’s wife (and daughter of Eugene O’Neill), while Noll (“Ragtime”) is set to portray Chaplin’s mother.

Jim Borstelmann (“Young Frankenstein”), Michael McCormick (“Elf”) and Wayne Alan Wilcox (“The Normal Heart”) are also among the actors onboard for the Gotham production.

With music and lyrics by Christopher Curtis and book co-written by Thomas Meehan and Curtis, the Warren Carlyle-helmed “Chaplin” — which played La Jolla under the title “Limelight” — is one of the earliest offerings of the fall Broadway season, with the production starting previews Aug. 21 ahead of a Sept. 10 opening at the Barrymore Theater.
