What is the method for returning the rights to pirated movies after the producing company goes bankrupt?

If the movies you watched were forbidden, you must repent from watching them, and you have no right to demand anything from the company.

However, if the movies were not forbidden, but you infringed upon the rights of their owners through piracy, then you must repent and strive to restore the rights you violated, proportionate to the benefits you caused them to miss. If it is not possible to return the rights to their owners, then donate the equivalent amount as charity to the poor and needy on their behalf.
