Rescuing Private Renfall was among several Earth films transmitted to Home for study by Race psychologists interested in how Tosevites' popular culture perceived the Lizards. Ambassador Sam Yeager's diplomatic delegation asked for and were granted permission to view it when they learned that it was in the Race's possession.
Atvar, the first Fleetlord of the Conquest Fleet, stumbled upon the delegation party watching the movie, and was informed of the movie's plot. However, after seeing the depiction of the Race soldiers as being shown as being more aggressive in the movie, Atvar argued this to Yeager as inaccurate, and pointed out that Earth films usually depicted the Lizards as either evil or stupid. The two debated over the media's depiction of their respective species, and concluded that both were good at depicting their enemies in a dim light.
The movie was shown in its original English with subtitles for Lizard audiences who did not speak the alien language. Subtitles on videos were among the many artifacts which had been all but lost to the Race before contact with the Tosevites once again forced them to treat foreigners as equals.
Rescuing Private Renfall is a reference and homage to the OTL movie Saving Private Ryan, screenwritten by Robert Rodat. Matt Damon, who played the title character in Ryan, is acknowledged in Homeward Bound as being a famous actor in the Worldwar timeline as well. It is not clear whether the Worldwar version of Damon appeared in Renfall, however.
