Nicholas Campbell filmed three episodes as The Hitchhiker, but in syndication, he has been edited out of the first two and his scenes re-shot with Page Fletcher. This episode is the only one of the three to still feature the original opening credits with Campbell, as well as feature Campbell as The Hitchhiker. As such, this is the only episode of the series that Page Fletcher does not appear in. It is unknown if this one was ever re-shot with Fletcher.
Real life sisters Audrey and Judy Landers play twins, but in real life they're two years apart.
One of the three assistant directors for this episode was actor Patrick Duffy (of "Dallas" and "Step By Step" fame), although he does not appear in it.
