The New York Times though, regretted that the film was "not up to the mark set by the Teutonic work, for the studio acoustics appear to be faulty and in several sequences the director, Victor Saville, has failed to have his scenes as adequately lighted," although the reviewer praised the work of Jack Hulbert and Owen Nares, concluding that "Both give clever performances, the result being that this Gainsborough feature makes for quite a good hour or so of entertainment";^[6] and the Motion Picture Herald praised the film as having "a sparkle in every foot."^[7]
