In 1945, screenwriter Monte Brice went through older RKO scripts to find a new idea for Brown & Carney's next movie and combined plot elements from Jack Oakie's Super-Sleuth (1937) and Wheeler and Woolsey's The Nitwits (1935).
On occasion Brown and Carney appeared in the same film but not together (Mexican Spitfire's Blessed Event, Vacation in Reno).
For 1961's The Absent-Minded Professor, they were listed in promotional material as "the comedy team of Brown and Carney" as though it was designed as a comeback, but they shared no scenes.
After the team's split, Brown continued working in films and appeared on television shows such as I Married Joan, Wagon Train, and My Three Sons until his death in 1961.
Zombies on Broadway is available as part of the “Karloff & Lugosi Horror Classics” DVD set, released by Warner Home Video in October 2009.
