Nason, a graduate of the Boston Conservatory, previously portrayed Lionel in the national tour of Rodgers and Hammerstein's Cinderella, and appeared in regional productions of Titanic, Side Show, The Wiz, and A Chorus Line. The two-time Boston Pops soloist can currently be seen appearing in the Julie Taymor film "Across the Universe." Walmartopia will mark Nason's Off-Broadway debut.

Nason is scheduled to begin performances the week of Oct. 10, assuming the roles previously played by the late Brennen Leath. Leath, an original Walmartopia cast member, died of complications from diabetes following the Sept. 22 evening performance of the musical. He was 25.

Walmartopia currently stars Cheryl Freeman (Tommy, The Civil War) and Nikki M. James (The Wiz, All Shook Up) as the mother and daughter who are at the center of this lampoon of big business.

The cast also features Sarah Bolt, Bradley Dean (Company), Stephen DeRosa (Into the Woods, Hairspray), John Jellison (All Shook Up), Andrew Polk, Pearl Sun (How the Grinch Stole Christmas!), Scotty Watson and Helene Yorke. Watson plays the late Wal-Mart founder, Sam Walton.

According to production notes, "Walmartopia tells the hilarious and timely tale of Vicki Latrell, a single mom and Wal-Mart employee who speaks out against her company's working conditions and finds herself and her young daughter jettisoned to 2037, into a future where Wal-Mart dominates the entire world." The Walmartopia creative team includes David Korins (sets), Miranda Hoffman (costumes) and Ben Stanton (lights), and is produced by WMtopia, LLC.

Walmartopia plays the following performance schedule: Tuesdays through Saturdays at 8 PM, Sundays at 7 PM, with matinees on Saturdays and Sundays at 3 PM. Tickets are priced at $65 & $45, and may be purchased online at Ticketmaster.com or by calling (212) 307-4100.
