Trivia

Although filmed during World War II, with a plot about a race to the death against Nazi spies, the words "Nazi" and "Germany" are never spoken in the movie. Bob Hope does come close when he calls the villains "nasties" in the climax, "nasty" being a vocal anagram of Nazi.

"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on October 19, 1942 with Bob Hope reprising his film role.

While singing "When Irish Eyes Are Smiling" on the bus, Bob Hope imitates Bing Crosby's "boo-boo-boo" singing style.

This film has a 100% rating based on 7 critic reviews on Rotten Tomatoes.
