When the Citadel Film Series book The Films Of Kirk Douglas was first issued, To Catch A Spy had been released in Europe, but not in America. It seems to have had very limited showings on this side of the pond.
The film is a lightweight spoof of the Cold War with Marlene Joubet a French girl married to a British subject trying desperately hard to get her husband back who has been arrested for espionage. Turns out he's made a deal with the Soviets and was deliberately arrested so they could affect a prisoner exchange. When the original exchange doesn't work out due to the most hilarious sequence in the film, Joubet looks to affect her own exchange and settles on Kirk Douglas, a most mysterious Romanian who keeps showing up all the time. She has to because her uncle, a member of Parliament played by Trevor Howard can't seem to close the deal.
Some nice location shooting in several spots in Europe is the best thing this film. The players look truly bored with this project and just phone in the performances.
To Catch A Spy will never make anyone's top 10 list of best Kirk Douglas films.
