One for the studio and one for you. That's the mantra for actors/writers/directors who want to achieve some modicum of success while maintaining artistic credibility. The idea is intriguing yet the execution rarely works as described. Should the "one for Hollywood" succeed, sequels are greenlit, franchises are spawned and then one turns to three or four. Jon Favreau made his one for Hollywood, it was titled Iron Man. Two years later the sequel was met with much less fanfare.
