Rodent to Stardom is a 1967 Warner Bros. Looney Tunes cartoon directed by Alex Lovy.
[1] The short was released on September 23, 1967, and stars Daffy Duck and Speedy Gonzales.
[2] It is the first cartoon to credit Warner Bros.-Seven Arts, but still uses the "Abstract WB" titles.
Daffy is plucked for stardom by director Harvey Hassenpfeffer of Colossal Studios — or so he thinks.
Daffy gets the love scene with Ducky Lamour, but after a number of stunts and just before the kiss, his stand-in, Speedy, takes over, and tells the duck, "There's no business like show business, eh, Señores Daffy?"
