In 1944 producer Walt Mattox hired Eddie Dean to support cowboy star Ken Maynard in the low-budget feature Harmony Trail.

The series limped to its conclusion with The Tioga Kid (1948), with Dean and some of the supporting cast members dressed to match their appearances in an older film.

(His 1944 feature Harmony Trail was re-released in 1947 to capitalize on his new movie fame, with Dean now billed as the star and the film retitled White Stallion.)

In 1950 he starred in two half-hour experiments for an early TV series, The Marshal of Gunsight Pass; these were unusual in that they were broadcast live, and any mistakes went out over the air.

Movie producer Ron Ormond gave Dean a specialty number in his vaudeville revue Varieties on Parade in 1951, but no further work was forthcoming.
