15It's the most successful independent film of all time
It's no secret that this movie made a metric ton of money. It was #1 at the box office when it opened in 1990 and went on to become one of the top ten money makers of the year; then there were all the tie-ins like toys, promotional materials, and VHS
sales. This movie came out when TMNT-mania was in full swing, and it definitely shows!
Which is why it is so hard to fathom that the first TMNT movie is considered an independent film. When the movie was being shopped to different production companies, they were fearful that it was going to be a flop. The film finally found a home at then-independent New Line Cinema; the company invested just $13.5 million and got a return of $202 million plus merchandise sales. This profit made Teenage Mutant Ninja Turtles: The Movie the most successful independent film of all time.
