The Night Invader

The Monthly Film Bulletin wrote: "David Farrar rather steals this fast-moving and amusing film from Anne Crawford, while Karl Jaffe is excellent as a bombastic but blundering German colonel even if he slightly burlesques it. The finish is rather incredible, but the swift dialogue almost masks its weakness. A special word should be given to small-part actor George Carney who is superb as a train conductor."^[5]

Kine Weekly wrote: "The actual plot is somewhat stereotyped, but the director and principal players cunningly disarm criticism and give it pace and punch by successfully adopting tongue-in-the-cheek methods. Its exuberant sense of humour and its well-timed thrills and hair-raising aerial climax will get it over with the industrial masses and youngsters."^[6]

Picture Show wrote: "Somewhat lurid and unconvincing is this spy melodrama ... there's plenty of action and narrow escapes from death before the hero does his stuff and returns triumphant. Briskly directed, heartily acted."^[7]

Picturegoer wrote: "Conventional plot concerning the adventures of a young British secret agent whose work takes him to Holland and Paris. It has familiar undercover thrills of a popular order. It smacks of the old-time serial melodrama, but is well put over nonetheless. David Farrar is good in the lead, and Anne Crawford supplies glamour as the heroine."^[8]
