Own the rights?
The titles say the film is "based on" the novel by R. L. Stevenson. That seems to mean they chose the same names for the characters. As the film progresses, the plot diverges more and more from the novel. The end is completely different and gave me the impression the budget ran out and they had to kill the cast off and finish the film as quickly as possible rather than stick to the story. I watched them making the film on the Isle of Man and bought the DVD to see what they had produced. I can't think of any other reason to buy it.
