I once saw a movie but I don't know the name for it and would like to find out. It was a color film from the mid 1960's to the early 1970's judging from the film content. It appears to have been filmed in Africa. The plot line revolves around two African native brothers around the ages of 6 and 3. I think they were accidentally separated from their family. These boys end up traveling the countryside of Africa ending up in little 'mini adventures' along the way, hitching rides along the way, even ending up riding along with some sore of military convoy. The father is trying to track them down, and seems to just miss every place he looks. The father runs from point to point barefooted searching for the boys. There is very little verbal dialog throughout the film.

I am looking for the title of a TV show I watched as a kid, probably early 80's, maybe late 70's. It was live actors with puppets. I'm pretty sure it took place on an asteroid, and they showed the live actors going there during the show's opening. I think one puppet was an orangutan. What I remember most was that one segment of the show was the "No Gnews Show, with Gary Gnu." Which always ended with "No gnews, is good gnews, with Gary Gnu."
