First credited film appearance of Clint Eastwood as Jonesey.
In Retour vers le futur 3 (1990), this film, Ma and Pa Kettle at Waikiki (1955) and Deux nigauds et la momie (1955) are playing at the Pohatchee Drive-In Theater in Hill Valley on November 16, 1955.
With Donald O'Connor's DUKW (duck) having stalled for want of gasoline, Francis comes along and asks him "Wanna sell a duck?" This clever play on words was a reference to a catchphrase of the late comedian Joe Penner "Wanna buy a duck?"
Clint Eastwood would later appear as himself in Clint Eastwood Meets Mister Ed (1962), an episode of Arthur Lubin's subsequent TV series Mister Ed (1961).
