Producing a successful film or television show is a massive undertaking. There are a lot of moving parts, and every one of those details cost a serious chunk of change. Creators must stay within the budget that they're provided by the studio, and at the end of the day, its success is based on how much money it grosses upon release.

This means that mishaps should be kept to a minimum, for fear of losing already-precious money. While accidents are inevitable, some are more expensive than others. These mistakes during filming ended up costing studios a whole lot of money.

You won't believe the injury that resulted in a lawsuit on the set of Ghostland.

The Marvel Comic Iron Man film series has been a major success from the start. The films have always done well in the box office as well as entertained fans without any major problems. However, while filming for Iron Man 3, Robert Downey Jr., who plays Tony Stark, severely injured his ankle when filming an action sequence.

At that point, they had no choice but to wait for his ankle to heal in order to resume filming. The healing process took six weeks, which ended up costing the film thousands of dollars waiting around for his recovery.
