First credited film appearance of Clint Eastwood as Jonesey.
In Back to the Future Part III (1990), this film, Ma and Pa Kettle at Waikiki (1955) and Abbott and Costello Meet the Mummy (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).
