Answer
The answer is "*Robin and the 7 Hoods*". Barbara's appearance in this 1964 film featured a star-studded cast, including Frank Sinatra, Dean Martin, and Bing Crosby. The movie adds a comedic twist to the classic Robin Hood tale set in prohibition-era Chicago, where Robin and his band of merry men steal from the rich to give to the poor in a bid to overthrow a corrupt political boss.
