"Miss Robin Crusoe" is a film where the original story was reworked into a watchable but ultimately dopey movie. It begins with Robin (Amanda Blake) getting washed up on an unchartered island. Eventually, the place is invaded by evil savages and Robin fights them off...and rescues a native. Soon, she (expectedly) names her new acquisition 'Friday' and they have a pretty cool life together until a man (George Nader) arrives....and Friday and Robin distrust him and his motives.
Back in the day, getting the look right meant very little in films. Here, like many jungle films, they combine animals from Africa AND other continents (such as Australia). And, the same goes for the 'natives'--who don't look Polynesian or Melanesian....just like black American actors. It really was sloppy. They also have muskets that magically reload themselves in seconds (an actual one took at least 30 seconds...and only that quickly if the person was an expert).
Now as to the story...well, it was pretty silly and dumb. My advice is to see the much better Luis Buñuel version with Dan O'Herlihy...it's much closer to the book, less silly and less formulaic. Also, this 1954 version could easily be seen as a bit racist today....and with good reason. Overall, a silly and forgettable film.
