As previously reported, Borle, who also starred as Max Dettweiler in NBC's 2013 broadcast of The Sound of Music, was in negotiations to portray the comedic sidekick to Christopher Walken's Captain Hook. "Girls" star Allison Williams will fly in the musical's title role.

Walken, Williams and Borle are the only three confirmed on the NBC website for Peter Pan Live!

Borle earned a Tony Award for portraying Black Stache (the inspiration for Captain Hook) in the stage production of Peter and the Starcatchers, which imagines the origins of the Peter Pan tale. He also starred on the NBC musical drama "Smash." 

Both "Smash" and "The Sound of Music Live!" were produced by "Peter Pan" producers Neil Meron and Craig Zadan.

The original Broadway production of Peter Pan, directed and choreographed by Jerome Robbins and featuring the songs “I’m Flying,” “I’ve Gotta Crow,” “I Won’t Grow Up,” and “Never Never Land,” opened on Broadway in 1954. The show had a book by J.M. Barrie and a score by Mark “Moose” Charlap and Carolyn Leigh, with additional songs by Jule Styne and  Betty Comden and Adolph Green. It starred Mary Martin as Peter and Cyril Ritchard as Captain Hook, both of whom won Tony Awards for their performances. Martin and Ritchard reprised their Broadway roles in a live telecast of the production, which aired on NBC in 1955. The production was so popular that NBC followed it in 1956 with a second live telecast — and in 1960 with a videotaped version, both also starring Martin and Ritchard. The 1960 videotaped version was rebroadcast in 1963, 1966 and 1973 and was released on home video in 1990.
