It's probably just because he made enough money from that stupid boxing reality show to produce it himself... since no one else would touch it. I mean really, Stallone was made through two series' of movies: Rocky and Rambo. I admit, Rocky I-III were good, and Rocky IV is even a guilty pleasure of mine... I like seeing us kick those commies asses, but seriously, after the disaster that was Rocky V, I can hardly believe it.
I guess he's hoping people had forgotten about that one by now.
