A number of Broadway tuner veterans — including Christian Hoff, Terrence Mann and Barbara Walsh — have lined up to perform in the Festival of New Musicals produced annually by the National Alliance for Musical Theater.

Event showcases eight tuners each year for a crowd of NAMT members that includes producers and presenters from around the country.

Hoff (“Jersey Boys”) will appear alongside Nancy Opel (“Urinetown”) and Stephanie D’Abruzzo (“Avenue Q”), among others, in “Heartbreakers,” based on the 2001 screen comedy, while Mann (“The Addams Family”) stars in “The Giver” with a cast that includes Heather Matarazzo.

Meanwhile, Walsh (“Company”) and Matthew Hydzik (“West Side Story”) are set for “The Trouble with Doug,” helmed by Victoria Clark, the tuner actress who toplined “The Light in the Piazza.”

Also among the thesps on tap for the festival are Curtis Holbrook (“Xanadu”) in “The Bowery Boys,” Nancy Anderson (“Yank!”) in “Play It Cool” and Kenita R. Miller (“The Color Purple”) and J. Bernard Calloway (“Memphis”) in “Red Clay.”

The 22nd outing of the NAMT fest runs Oct. 21-22. Prior editions have yielded Broadway fare including “The Drowsy Chaperone” and “Thoroughly Modern Millie.”
