That's been Universal's issue for years. Besides F&F and JP, they really don't have a ton of huge adult franchises under their belt. However, they have been making some inroads with Nintendo...I know he's a fan of F&F but I highly doubt he'd actually direct one. Jurassic Park doesn't seem like an IP he'd be interested in as well. What other IP's do Universal have?
Christopher Nolan's Metroid? Is that anything?
