Seagal, Lungren, and Van Damme make a ton of money doing "direct to DVD" movies, selling and viewing them in countries other than the United States to which they make a shitload of money because their movie that would be considered "shitty" in the United States would be considered a masterpiece in a country like India or Malaysia where the quality of the movies are much worse along with being treated like gods in that country allowing them to get away with all sorts of stuff making production less expensive than what's written on the books.
In addition, they have off-shore accounts to deposit their cash so they can avoid taxes and licensing fees. They are worth a lot more than they appear. Seagal is not as dumb as he looks.
