Gerald McBoing! Boing! on Planet Moo (1956)

"Gerald" is the kid who speaks in sound effects, and the press go mad when he is abducted by a flying saucer. He is taken to the far away planet of "Moo" where the king (straight off a suite of playing cards) turns out to be a bit broke. He and his advisors decide that Earth is ripe for the picking so interrogates the incomprehensible child, only to conclude that being friends might be better and so he, his aide "Murdoch" and the young "Gerald" set off to visit Earth and do a deal - "boinga boinga" style. I found this a bit dull and repetitive, though it does illustrate the difficulties of communication when language is not a constant. Watchable, but nothing special.
