Fantastic Four hasn't been a big seller for a while, but I have to believe if Marvel had the rights to do a film they would be putting a lot more weight behind them, putting A-list talent on the books, making them more central to storylines that might be adapted for future films, etc. Right now though, investing that talent and focus on a property they don't have film rights to doesn't make sense when you consider their paltry funny book profits against Disney's film interests.
