Lewis and Boggess, who will star in the respective roles of The Phantom and Christine, previously co-starred in the father-daughter roles of King Triton and Ariel, respectively, in the 2007 Broadway production of The Little Mermaid.
Lewis will become the first African-American performer to star as the Phantom in the New York production. Tony Award nominee Robert Guillaume succeeded original star Michael Crawford in the Los Angeles production.
The engagement marks Boggess' return to the musical, following her appearance in the 25th Anniversary Broadway cast of Phantom in 2013, as well as the 25th Anniversary production at London's Royal Albert Hall.
"Having worked with Norm since the 90s, when he played John in Miss Saigon on Broadway, and then Javert on Broadway in Les Misérables in 2006, I couldn’t be more thrilled that he is now joining Phantom, matched with Sierra – one of the finest Christines ever. It’s hard to imagine a more exciting pairing, as the show continues its phenomenal, history-making run at The Majestic," producer Cameron Mackintosh said in a statement
Lewis, who earned a Tony nomination for Porgy and Bess, has also bee seen in the 25th anniversary concert of Les Misérables, as well as Sondheim on Sondheim, Side Show, The Wild Party, Dessa Rose and Miss Saigon.
Boggess has also been seen on Broadway in Master Class. She also starred in the London world premiere of the Phantom sequel, Love Never Dies and the original Las Vegas production of Phantom.
