Intersting factiod No. 132456: Stallone played Rocky as a lean mean 195lb fighter for the Rematch with Clubber Lang. In reality, stallone dropped to just 155lbs to achieve the uber ripped, 'post Apollo training' visual effect.
I think the title being 'Rocky Balboa' with no numbers or tag lines indicates that he is trying to bring the character full circle, and return to the roots of the first movie. Lest we forget that, back in the late 70's after Rocky 1, Sly was tipped to be 'the new DeNiro', and 'Copland' showed he is far more than a one dimensional action man.
He is in good shape, and I feel that this, and Rambo 4 will suprise a lot of people both in their quality, and their tone.
