About how much money did it cost for Tommy Wiseau to make his masterpiece "The Room" (2003)?

It is estimated that Tommy Wiseau spent around $6 million to make his critically panned yet cult classic film "The Room" in 2003. The high cost was mainly attributed to Wiseau's determination to use the best equipment available, including filming simultaneously with both 35mm and HD cameras, hiring a professional crew, extended shooting schedules, multiple sets, and an array of expensive props and furnishings. Wiseau also reportedly self-financed the entire project, and the exact breakdown of the budget remains largely unknown, adding to the mystique surrounding the film's creation.
