Voice Acting with Sunday Muse
Sunday coached me privately for the Happy Madison/Netflix musical film called LEO starring Adam Sandler, Jason Alexander, Bill Burr, Cecily Strong. Our coaching session brought me so much confidence that I was able to bring my full, joyful self to the five-hour scratch record and book the role of Mrs. Salinas from my closet booth—I even got a song on the movie soundtrack! It was released on Thanksgiving and is Netflix’s biggest animated debut!
~ Allison Strong (The Marvelous Mrs. Maisel & Broadway's Mamma Mia)
