Although he received no on-screen credit for his role as "Billy Kettle" in
Ma and Pa Kettle Back on the Farm (1951), he is probably the one most remembered portraying that part. Sloane is also one of the youngest actors to have ever been under contract to Universal Pictures. Notwithstanding the "Official Kettle Family Portrait", director
Edward Sedgwick insisted that the young Sloane be the only child used exclusively for publicity pictures promoting the film.
