Satz played the male lead in the 1931 film His Wife's Lover (Zayn Vaybs Lubovnik), which was billed as the "first Jewish musical comedy talking picture". He also played on Broadway, one of his more noted roles being Abe Potash in the 1926 Potash and Perlmuter of A. H. Woods.

He starred in A Galitsianer Khasene (A wedding in Galitsia) (music by Herman Wohl, lyrics Boris Rozenthal) with Zina Goldstein and in Ven di zun geyt oyf (Sunrise) with Ola Lilith. His last role was in The Golden Land at the Public Theatre in 1943.
