The sequel Journey to the Center of the Earth provides examples of:
- Troubled Production: The movie was nearly finished but The Cannon Group was hemorrhaging money and couldn't afford the special effect shots, of which there where many. Having to fulfill contractual commitments to foreign distributors who had already purchased the film, Cannon went to their usual to-go guy, Albert Pyun, and tasked him to basically finish the film using as much of the existing footage as possible. Also, the budget for the reshoots was a joke. How much of the footage was Pyun's and how much was Lemorande's is currently unknown, although Rusty claims only the first 8 minutes were his.
