Sunny, the third successive picturization of a musical comedy by the English team of producer-director Herbert Wilcox and star Anna Neagle, is a typical operetta Cinderella tale.
Despite the limitations imposed on producer-director Wilcox by transference of lightly-moulded musical comedy plot, he gets the maximum out of the dancing abilities of Ray Bolger, who scores in three solo routines and teams up with Neagle for a pair of numbers.
The Cinderella adventures of Sunny are set in New Orleans during Mardi Gras festivities. Neagle is the star of a streamlined circus. She meets, falls in love and becomes engaged to John Carroll, heir to an auto fortune. Ditching the circus, she accompanies him to the family mansion to meet the relatives, especially gruff and eccentric auntie (Helen Westley). Wedding ceremony is blown up by premature arrival and celebration of the bride’s circus friends.
More important than Neagle’s standard performance in the title spot is the sterling performance of John Carroll, who gaily romps through as the young millionaire.
