This short came about from Maurice LaMarche's inspiration for the Brain's voice. When he came into the studio to audition, he unexpectedly did an impression of Orson Welles. LaMarche had perfected this impression by memorizing the original Welles outtakes and performing them by himself. After securing the role of the Brain, LaMarche would warm up his voice by reciting parts of Welles' outtakes whenever he came to the studio to record.
The title is a pun on The Brave Little Toaster (1987), which writer Deanna Oliver provided her voice of the title character for.
In the beginning, the people that Brain fires are producer and creator Tom Ruegger, writer Peter Hastings and voice director Andrea Romano, all of whom voice themselves. The engineer is a caricature of real life engineer Harry Andronis, who also voices himself.
This is the first Warners segment in the series to not feature Yakko and Dot.
Some of Welles' dialogue was cleaned up for this version. He originally says, "Get me a jury that can 'In July' and I'll...go down on you." which was changed to "...I'll...make cheese with you." Additionally, he drops two S-bombs in the recording. The first time, it is replaced with "Shoot!" and the second time he says, "This is a lot of tripe, you know that?" Welles saying "Jesus!" is censored to "Jiminy!"
