First of all, I must confess that I haven't seen the original Chevalier film on which "On the Riviera" is based. However, Fox recycled the plot before this film for "That Night in Rio" with Don Ameche, Alice Faye, and Carmen Miranda in the Danny Kaye, Gene Tierney, and Corinne Calvet roles. I think "Rio" is far superior to "Riviera." The plot is much better paced, less frantic and frenetic (although that may simply be the difference between Ameche and Kaye as performers). For me, a little Kaye "shtick" goes a long way, and the more he uses it, the less amused I get. In this film, he lays it on with a trowel. Fox dipped into the well once too often. The only saving grace is the lustrous Tierney in luscious color.
