Lea Michele will reveal songs from the 3D animated musical, ‘Dorothy of Oz’ at this Saturday’s Comic Con in San Diego, California.

The film features the Glee star and Broadway veteran in the title role and will be released early next spring. She will debut a song from the film alongside fellow Broadway actress, Megan Hilty. 

Songwriter Bryan Adams has contributed original songs for the film with co-writer Jim Vallance.

Hugh Dancy and Martin Short are set to join Michele in the new musical and Sony will release the soundtrack next year.
