I still remember watching Richie Rich in cinema as a kid. The one and only thing I remembered from the movie, watching it 25 years later, was the fact that Richie had his own McDonald's. That was a very vivid memory.
Also, I thought that this movie would be quite bad and it's really the opposite! The story, while not original, is interesting and the movie is well produced.
And the final sequence on the fake Mount Rushmore is obviously a nice hommage to Hitchcock.
