Guest star Jack Colvin, who played the Nazi defector Luden, is perhaps best remembered for playing investigative reporter Jack McGee, the man who relentlessly dogged the trail of Dr. David Banner for five seasons on The Incredible Hulk (1978).
This raid marks the return to the series of its third-billed star Eric Braeden, who was absent from the previous seven episodes. During his furlough, he guest starred in The Short Tail Spy (1966).
