He provided the deep voice for Stan Laurel's performance of "The Trail of the Lonesome Pine" in Way Out West (1937), in which the Avalon Boys Quartet appeared.

His publicity agent, Wojciechowicz "Bow Wow" Wojtkiewicz (former husband of gossip columnist Sheilah Graham),[2] accepted blame for the ill-advised effort, claiming that Wills knew nothing about it.

As was customary at the time, Wills was given no billing for his vocal work, though he was featured prominently on-screen as blustery General Ben Kaye in the fourth entry, Francis Joins the WACS.

[citation needed] In Rory Calhoun's Western series The Texan, Wills appeared in the lead role in the 1960 episode titled "The Eyes of Captain Wylie".

In 1962 he guest-starred as title character “Abe Blocker” on Gunsmoke, as a deranged mountain man, and old friend of Matt Dillon, preying on homesteaders.

[citation needed] In 1971, he appeared as Pat Reedy on The Men from Shiloh (rebranded name of the TV Western The Virginian) in the episode titled "The Angus Killer".
