The Counterfeit Traitor (1962)

Set during WWII, an American born businessman (William Holden), now a Swedish citizen, is essentially blackmailed by British agents into spying for them on his business trips to Nazi Germany. He must pass himself off as a Nazi sympathizer which has repercussions on his marital and personal life. Based on the non fiction book by Alexander Klein and directed by George Seaton (AIRPORT). An interesting real life tale of espionage is very well acted (especially by Holden) but Seaton's lethargic pacing almost does the movie in. This should be a lean and taut spy film but Seaton treats it as if it were an epic (it runs near 2 1/2 hours) and we get too much unnecessary details and an overabundance of establishing scenic shots which makes it hard to sustain interest. The authentic locations (Germany, Sweden, Denmark) give the film some much needed atmosphere and Alfred Newman's score is an asset. With Lilli Palmer, Hugh Griffith, Klaus Kinski, Werner Peters, Wolfgang Preiss, Ingrid Van Bergen and Eva Dahlbeck (wasted though I suspect she ended up on the cutting room floor).
