Ice-Capades (1941)

Bob Clemens is a cameraman for newsreels. Assigned to shoot the Swiss ice skater Karen Vadja, he arrives too late, so decides to film a woman skating on a different New York rink and pass her off as Karen. The scheme backfires when promoter Larry Herman takes a look at Bob's film and decides to make the skater a star. Unfortunately, it's actually amateur (and illegal immigrant) Marie Bergin in the newsreel footage, not the great figure skater from Switzerland. Chaos ensues as Bob tries to straighten everybody out.
