The fact that the US space program was kicked off by a Nazi who was let off because he was useful was made famous by Tom Lehrer. However the comparison between these two films rams the point home.
At top is color film from 1944 showing Von Braun as a Nazi, testing the V2.
And a Walt Disney space series from 1955, where Von Braun himself talks about space rockets.
